A Faster Way to Switch Between Compatible Trailers
One of the most common frustrations in towing is the need to switch hitch balls for different trailers. Trailer couplers may require different ball diameters, regardless of trailer type. A conventional setup may therefore require changing the hitch ball or replacing the entire ball mount. A multi-ball mount reduces the number of separate components needed when the towing vehicle is used with several compatible trailers.
The Three-Ball Trailer Hitch Mount with U-Clevis is designed to simplify switching among compatible trailers. It allows the user to select among three ball diameters and one clevis connection by rotating the mount, subject to coupler compatibility, correct towing height, adequate clearance, and the rating of every component in the towing system.
It is a multi-interface ball mount intended to reduce the number of separate mounts needed for compatible trailers.
What Is a Three-Ball Trailer Hitch Mount with U-Clevis?
One Mount, Four Connection Options
A Three-Ball Trailer Hitch with U-Clevis is an integrated towing connection device that combines three different sizes of trailer balls with a U-shaped clevis (U-Clevis) on a single shank. With just one product, users can cover both ball-type couplers and lunette ring couplers. Compatibility with a lunette or drawbar eye must be confirmed from the mount manufacturer’s specified eye dimensions, pin diameter, articulation limits, and rated capacity.
Main Components and Connection Positions
The structure of a Three-Ball Trailer Hitch Mount with U-Clevis can be broken down into the following core components:
① Three Hitch Balls
The three-ball design is the core functional module of this product. The three balls correspond to the three most common trailer coupler sizes:
| Ball Size | Application | Common Capacity Range |
| 1-7/8″ (approx. 47.6mm) | Light-duty towing – motorcycle trailers, small utility trailers | 2,000 – 3,500 lbs |
| 2″ (approx. 50.8mm) | Most common size – boat trailers, campers, medium equipment trailers | 3,500 – 12,000 lbs |
| 2-5/16″ (approx. 58.7mm) | Heavy-duty towing – large RVs, heavy equipment trailers | 6,000 – 30,000 lbs |
Ball diameter indicates coupler fit, not towing capacity. Never exceed the lowest rating of the tow vehicle, receiver, mount, selected ball or clevis connection, trailer coupler, or any other load-bearing component.
The three balls are fixed at different rotational positions on the same mount. To select another connection position, the vehicle and trailer must first be stationary and the connection fully unloaded. The user can then remove the receiver pin, rotate the mount to the required position, reinstall the correctly rated pin, and secure it with the specified retaining clip. Before towing, confirm that the selected ball or clevis is correctly oriented and that the unused connection points do not interfere with the trailer tongue, jack, bumper, or ground.
② U-Clevis
What Is a U-Clevis? A U-Clevis is a mechanical connector named for its shape –a clevis coupling uses two parallel ears and a transverse pin to connect a dimensionally compatible drawbar eye. Its permitted road, agricultural, or off-road use depends on the coupling design, the mating eye and the manufacturer’s approval.
How a U-Clevis works is straightforward:
Before connecting, verify that the drawbar eye dimensions, clevis opening, pin diameter, articulation limits, and rated capacities are mutually compatible. With the vehicle and trailer secured and the connection unloaded, position the approved drawbar eye between the clevis ears, insert the manufacturer-specified load-bearing pin through both ears and the eye, and install the correct retaining clip or cotter pin. Complete all required safety-chain, braking, breakaway, and electrical connections before towing.
③ Shank
The shank connects the entire assembly to the vehicle. The T28674 uses a standard 2″ × 2″ square tube design, which fits a compatible 2-inch receiver. The solid construction provides higher torsional strength and load-bearing stability.
How It Differs from Conventional Trailer Hitches
To better understand the positioning of products like the T28674, it is helpful to compare them with other common types of trailer hitches on the market.
Comparison 1: vs. Single-Ball Trailer Hitch
| Aspect | Single-Ball Hitch | Three-Ball Hitch with U-Clevis |
| Number of balls | 1 | 3 (1-7/8″, 2″, 2-5/16″) |
| Connection types | Ball only | Ball + U-Clevis |
| Trailer compatibility | Single size | Multiple sizes + U-Clevis trailers |
| Switching convenience | Must wrench-swap balls or ball mount | Rotate shank to switch |
Key difference: A single-ball hitch can only tow trailers of one coupler size. If you have two trailers – one with a 2″ coupler and one with a 2-5/16″ coupler – you need either two separate drawbars or a wrench on hand to swap balls. The Three-Ball Hitch integrates all three sizes on one shank – rotate to switch, reducing the number of independent trailer hitch mounts.
Comparison 2: vs. Standard Three-Ball Trailer Hitch (without U-Clevis)
| Aspect | Standard Three-Ball Hitch | Three-Ball Hitch with U-Clevis |
| Number of balls | 3 | 3 |
| U-Clevis | No | Yes |
| Application | Ball-coupler trailers only | Ball trailers + U-Clevis trailers |
| Coverage | Single connection type | Two connection types |
Key difference: A standard three-ball hitch, despite having three balls, can only be used for ball-type couplers. If your fleet includes agricultural or industrial trailers with lunette rings, a standard three-ball hitch cannot meet your needs. The U-Clevis on the Three-Ball Hitch is designed specifically to fill this gap – it allows the same drawbar to accommodate both ball couplers and lunette ring couplers.
Comparison 3: vs. Adjustable Trailer Hitch
| Aspect | Adjustable Trailer Hitch | Three-Ball Hitch Mount with U-Clevis |
| Height adjustment | Adjustable rise or drop | Fixed rise or drop |
| Connection options | Vary by model; may use single, dual, or interchangeable balls | Three integrated ball sizes plus one clevis connection |
| Switching method | Depends on the design and installed coupling module | Remove the receiver pin, rotate the unloaded mount, and reinstall the pin and retaining clip |
| Primary advantage | Helps keep trailers with different coupler heights approximately level | Provides convenient access to multiple compatible connection interfaces |
| Main limitation | Usually has more removable or adjustable components | Cannot compensate for significant differences in trailer coupler height |
An adjustable hitch mount allows the user to change the rise or drop so that trailers with different coupler heights can remain approximately level. Its ball configuration and switching method vary by product, so changing the ball does not always require a wrench. In contrast, the Three-Ball Hitch Mount with U-Clevis prioritizes interface selection: after the connection is fully unloaded, the user can remove the receiver pin, rotate the mount to the required ball or clevis position, and reinstall the pin and retaining clip. Its principal limitation is the fixed towing height. It should therefore be used only when the selected position provides the correct rise or drop, adequate ground clearance, and compatibility with the trailer’s coupler or drawbar eye.
Who Needs a Three-Ball Trailer Hitch with U-Clevis?
Based on the analysis above, the Three-Ball Trailer Hitch with U-Clevis is best suited for:
- Owners with multiple trailer types: Owners of multiple trailers whose couplers are marked for different ball diameters supported by the mount.
- Users who also tow agricultural/industrial trailers: Users who have a trailer equipped with a drawbar eye specifically approved for a clevis-and-pin connection may benefit from the clevis position.
- Practical-minded users who want “one mount for several compatible trailers”: No need to buy separate drawbars for each trailer, no wrenching every time you switch.
- Users frequently work outdoors or on job sites: Chrome finish offers excellent corrosion resistance in wet, muddy conditions.
Structure & Durability: Trade-offs in Different Designs
Structural Design and Rated Capacity
A multi-interface hitch mount combines several connection positions into one assembly, but its strength cannot be determined from its size, appearance, or weight alone. Load capacity depends on factors such as material grade, cross-sectional geometry, manufacturing method, weld or forging quality, pin-hole design, heat treatment, fatigue resistance, and the validation tests performed by the manufacturer.
For this reason, terms such as “solid,” “heavy-duty,” or “industrial-grade” should not be treated as proof of towing capacity. The relevant figures are the marked gross trailer weight (GTW) and maximum vertical or tongue-load rating for the exact product and, where applicable, for each individual ball or clevis position.
The towing limit of the complete setup is always determined by its lowest-rated component. This may include the tow vehicle, receiver hitch, ball mount, selected ball or clevis position, hitch pin, trailer coupler or drawbar eye, and other load-bearing components.
What Does a Product Weight of 7 kg Mean?
The T28674 is listed as weighing approximately 7 kg. This figure is useful when considering installation, removal, storage, and everyday handling, but it should not be used to estimate towing capacity.
Products of similar dimensions can have different ratings because of differences in material strength, cross-sectional design, manufacturing processes, weld quality, and fatigue performance. A heavier mount may simply contain more material, while a lighter mount may use a different material or a more efficient structural design. Neither weight alone establishes that one product is stronger or safer than another.
When comparing hitch mounts, users should prioritize verified GTW and maximum vertical-load ratings, compatible connection dimensions, applicable test information, and manufacturer instructions. Product weight should be treated only as a handling consideration.
Surface Finishes and Corrosion Protection
Surface treatment affects appearance, maintenance requirements, and resistance to environmental exposure. It does not determine the structural rating of a hitch mount. Actual corrosion performance depends on the coating system, coating thickness, surface preparation, adhesion, edge coverage, base material, operating environment, and maintenance.
| Finish | General Characteristics | Important Limitations | Typical Maintenance Considerations |
| Chrome-plated | Bright appearance and a protective plated surface | Chips, pores, or scratches may expose the steel substrate to localized corrosion | Clean and dry after exposure to moisture, mud, road salt, or coastal air |
| Powder-coated | Provides barrier protection and is available in different colors and textures | Deep scratches or coating damage can expose the underlying steel | Inspect damaged areas and repair them according to the manufacturer’s instructions |
| Zinc-plated | Provides a zinc barrier and limited sacrificial protection to exposed steel | Protection depends strongly on coating thickness and environmental exposure | Monitor for coating loss and white or red corrosion products |
| Hot-dip galvanized | Usually provides a thicker zinc coating than electroplated zinc | Surface appearance and dimensional tolerances may differ from plated finishes | Inspect high-wear areas and areas where the coating has been removed |
| Stainless steel | Corrosion resistance comes primarily from the alloy rather than an applied coating | Performance depends on the stainless-steel grade; chloride exposure may still cause localized corrosion | Clean after salt exposure and inspect for pitting, galling, or contamination |
Chrome plating can provide an attractive finish and useful corrosion protection under ordinary conditions. However, it should not be described as immune to rain, mud, road salt, or saltwater. If the coating is damaged and the carbon-steel substrate becomes exposed, localized corrosion may begin.
Powder coating provides barrier protection when the substrate preparation and curing process are adequate. Chips and deep scratches should be addressed because exposed carbon steel may corrode.
Zinc coatings can provide sacrificial protection to small exposed areas, but they do not make the component rust-proof. Electroplated zinc and hot-dip galvanizing should not be treated as identical processes because their coating thickness, appearance, and long-term performance can differ substantially.
Suitable stainless-steel grades can provide strong corrosion resistance, but stainless steel is not automatically the best choice for every hitch component. Material grade, mechanical strength, fabrication quality, susceptibility to galling, chloride exposure, and compatibility with adjacent metals must all be considered.
Choosing a Finish for the Intended Environment
Structural suitability should be evaluated before surface finish. First, confirm that the hitch mount has the required load ratings, receiver dimensions, rise or drop, connection geometry, and manufacturer approval for the intended trailer. Surface finish can then be considered according to the operating environment and expected maintenance.
For ordinary road use, a plated or powder-coated product may provide suitable protection when it is regularly cleaned and inspected. For frequent exposure to road salt, coastal air, or saltwater, users should look for documented corrosion-performance information rather than relying only on terms such as “chrome,” “zinc,” or “stainless steel.”
Regardless of finish, the mount should be rinsed with fresh water after salt exposure, dried when practical, and inspected for coating loss, rust, pitting, cracks, deformation, and excessive wear. Surface finish cannot compensate for an inadequate load rating or damaged structure.
Installation and Safe-Use Considerations
Confirm Receiver Fit and Towing Height
Verify that the mount is designed for the vehicle’s receiver opening and that the receiver pin has the correct diameter and effective length. A mount described as fitting a 2-inch receiver should be installed only in a compatible 2-inch receiver unless the manufacturer expressly approves another configuration.
Receiver size alone does not establish compatibility. The selected ball or clevis position must provide the correct rise or drop so that the loaded trailer remains approximately level. Adequate clearance is also required between the mount, bumper, trailer tongue, tongue jack, safety chains, and ground throughout the expected turning and articulation range.
Do not use an unapproved adapter to correct a receiver-size or height mismatch. Adapters may reduce clearance, introduce additional movement, or change the permitted capacity of the towing system.
Verify the Connection Interface
When using a hitch ball, match the ball diameter to the size marked on the trailer coupler. Confirm that the coupler closes and locks correctly and that both the selected ball position and the coupler have adequate ratings for the trailer.
When using the clevis position, verify the drawbar eye dimensions, pin diameter, clevis opening, permitted clearance, articulation limits, and rated capacities. A visible fit does not by itself establish safe compatibility. Do not assume that every lunette ring or drawbar eye is approved for use with the clevis.
Only the pin and retaining device specified or approved by the manufacturer should be used. Ordinary bolts, undersized pins, or unverified replacement hardware must not be substituted for a rated hitch or clevis pin.
Observe the Lowest-Rated-Component Rule
Never exceed the lowest rating of any component in the towing system. Check both the permitted gross trailer weight and the maximum vertical or tongue load.
Relevant limits may include those of the tow vehicle, receiver hitch, ball mount, selected ball or clevis position, hitch pin, trailer coupler or drawbar eye, safety chains, tires, axles, and braking system. The vehicle manufacturer’s towing capacity, gross combined weight rating, and loading requirements must also be observed.
Ball diameter is a compatibility dimension, not a towing-capacity rating. A larger ball does not automatically mean that the complete towing system can carry a heavier trailer.
Switch Positions Only When Fully Unloaded
The connection must be fully unloaded before the receiver pin is removed or the mount is rotated. Park the vehicle and trailer on stable ground, secure them against movement, and support the trailer tongue as required.
After rotating the mount, align the correct receiver-pin hole, insert the manufacturer-approved pin completely, and install its retaining clip. Confirm that the required ball or clevis position is correctly oriented and that unused connection points will not contact the trailer tongue, jack, bumper, or ground.
Never attempt to rotate the mount while it is supporting the trailer tongue or while the ball or clevis remains connected to the trailer.
Complete All Secondary Safety Connections
The primary ball or clevis connection is only one part of a complete towing setup. Install the required safety chains or cables at approved attachment points and provide only enough slack for normal turning without allowing the trailer tongue to contact the road if the primary connection fails.
Connect and test the trailer lighting, service brakes, and breakaway system when these are required for the trailer and jurisdiction. Requirements for safety chains, brakes, lighting, and breakaway devices vary by vehicle class and location, so users should follow the tow-vehicle manual, trailer manual, product instructions, and applicable laws.
Inspect Before Every Towing Operation
Before each towing operation, inspect the receiver, mount, balls, clevis ears, pins, retaining clips, welds, and mating coupler or drawbar eye. Do not use the equipment if there are cracks, bending, loose components, severe corrosion, material loss, enlarged or elongated holes, excessive play, or abnormal wear.
Confirm that:
- The correct connection position is selected.
- The coupler size matches the selected ball.
- The ball coupler is fully closed and locked, or the clevis pin is fully inserted and retained.
- The receiver pin and retaining clip are correctly installed.
- Safety chains, electrical connections, brakes, and the breakaway device are properly connected.
- The trailer is approximately level and has adequate clearance.
- The trailer load is secured, and all relevant weight limits are observed.
Clean the mount after exposure to mud, water, road salt, or saltwater. Lubricate only the locations and with the products recommended by the manufacturer, because unsuitable lubrication may attract abrasive contamination or interfere with some locking mechanisms.
Is a Three-Ball Hitch Mount with U-Clevis the Right Choice?
A Three-Ball Hitch Mount with U-Clevis may be useful for owners who regularly switch among several trailers with different, compatible connection interfaces. Its primary advantage is convenience: three ball diameters and one clevis position are available on a single rotating mount.
Before selecting one, confirm the following:
- Are the trailer couplers marked for ball diameters provided by the mount?
- Is any drawbar eye specifically compatible with the clevis opening and pin?
- Are the GTW and maximum vertical-load ratings adequate for every intended trailer?
- Does the fixed rise or drop allow each loaded trailer to remain approximately level?
- Is there adequate clearance for turning, articulation, the trailer jack, and ground obstacles?
- Are the receiver, pins, safety devices, brakes, and electrical connections compatible?
- Are manufacturer instructions and applicable local requirements available and understood?
If the receiver size, towing height, connection dimensions, articulation limits, clearances, and all relevant load ratings have been verified for each trailer, a three-ball mount with a clevis connection can reduce the number of separate mounts that need to be stored and handled.
It should not be treated as a universal towing solution. Final suitability depends on the complete vehicle–mount–trailer combination, the ratings of its individual components, the manufacturer’s instructions, and the conditions in which the equipment will be used.
