NBJINGYI 2-5/16" Adjustable Channel Mount Trailer Coupler - 15,000 lb Cast Steel, Sleeve-Lock, Black

The NBJINGYI 2-5/16" adjustable channel mount trailer coupler is a heavy-duty cast-steel sleeve-lock coupling rated to tow up to 15,000 pounds and includes a full mounting hardware kit for straightforward installation.

Designed for demanding towing tasks, this coupler swaps into standard channel-mount trailer tongues to provide a quieter, tighter ball connection than many pintle or worn couplers. Its adjustable channel design lets you fine-tune towing height for different trucks or tractors, while the sleeve-lock latch and safety pin secure the 2-5/16" hitch ball during long hauls and rough roads. A black powder-coated finish guards the cast steel body against abrasion and weather to extend service life in construction, agricultural, and transportation settings.

How does the adjustable channel mount improve trailer alignment?

The channel-mount format lets you slide and set the coupler along the trailer tongue channel to achieve the correct towing height without welding or permanent alterations. That adaptability keeps trailers level between different tow vehicles and helps maintain even tongue weight distribution.

• Slide-to-position channel for precise height changes
• Adjustable without cutting or complex modifications
• Better tongue weight balance across tow vehicles

What keeps the 2-5/16" ball locked securely during transit?

This coupler uses a sleeve-lock mechanism that clamps around the ball socket and is backed up by an included safety pin. The dual retention method reduces play and limits rattle or accidental disengagement when hauling heavy loads or traversing uneven terrain.

• Sleeve-lock centering and clamping action for a snug fit
• Included safety pin for redundant locking security
• Designed to minimize movement during long-distance or off-road towing

Is the coupler built to handle heavy commercial or agricultural loads?

Yes—constructed from high-strength cast steel and rated to 15,000 lbs, this coupler is intended for large equipment trailers, flatbeds, and heavy machinery transport. The robust body and industrial finish deliver the structural capacity needed for frequent heavy towing tasks.

• 15,000 lb gross towing capacity for demanding loads
• Cast-steel construction for high tensile and impact strength
• Powder-coated surface to resist abrasion and outdoor exposure

What comes with the coupler to make installation easier?

The package includes a complete set of mounting hardware sized for channel installations, so you can replace an existing coupler or upgrade from a pintle-style hitch without sourcing extra parts. Bolts, nuts, and the safety pin are supplied for a straightforward swap-in fit.

• Full mounting hardware kit for channel-mount installation
• Safety pin included for immediate securement
• Compatible with standard 2-5/16" hitch balls and channel tongues

Who this is for: The NBJINGYI 2-5/16" adjustable coupler is intended for fleet operators, contractors, farmers, and trailer owners who need a heavy-duty, low-maintenance ball coupling. If you haul heavy equipment, switch between multiple tow vehicles, or want a quieter, tighter connection than a worn pintle ring, this cast-steel, sleeve-lock coupler with included hardware offers a durable, install-ready solution.
