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

NBJINGYI's 2-5/16" adjustable channel-mount trailer coupler is a heavy-duty cast-steel sleeve-lock coupling engineered to secure up to 15,000 pounds for demanding towing jobs.

This coupler swaps into a channel-style mount and gives you height adjustability plus a sleeve-lock latch and safety pin for a tight, low-rattle connection to a 2-5/16" hitch ball. Built from cast steel and finished in black powder coat, the unit is made to withstand construction, agricultural, and long-haul environments while including the mounting hardware needed to replace older pintle rings or worn couplers.

How does the adjustable channel mount improve towing setup?

The channel-mount format lets you slide the coupler up or down within the trailer tongue channel, so you can match trailer height to different tow vehicles without fabricating new mounts. Adjustability helps keep trailers level, improving stability and reducing tongue weight surprises during hook-up.

• Fits standard channel tongues — slides for precise height positioning
• Simplifies compatibility across trucks, tractors, and equipment haulers
• Reduces need for shims or welded adapters
• Fastens secure with included mounting hardware

What safety features does the sleeve-lock mechanism offer?

The sleeve-lock system clamps over the hitch ball and locks the latch in place, creating two layers of retention when used with the supplied safety pin. This design minimizes movement and prevents accidental uncoupling under load or on rough roads.

• Sleeve-locking collar for a snug, vibration-resistant fit
• Included safety pin adds redundant security
• Cast-steel construction resists deformation under heavy loads
• Low-profile latch reduces snag points and road noise

Is this coupler durable enough for heavy-duty and outdoor use?

Yes—the coupler is cast from high-strength steel and finished with a uniform black powder coat to resist surface wear and corrosion in outdoor conditions. The robust materials and coating are chosen to stand up to frequent hookups, exposure to the elements, and rough job-site handling.

• Heavy cast-steel body rated to 15,000 pounds capacity
• Powder-coated finish for improved corrosion resistance
• Engineered to withstand vibration and off-road loading
• Quality hardware included to maintain structural integrity

What is included and how easy is installation?

The package contains the coupler and a full set of mounting bolts and fasteners designed to fit standard channel-mount tongues, so you can replace an existing ring or coupler without sourcing extra parts. Installation requires basic tools and standard torque practices; follow vehicle and trailer manufacturer specs for bolt torque and safety checks.

• Complete mounting hardware kit for straightforward installation
• Designed as a drop-in replacement for many channel mounts
• Minimal fabrication typically required—bolts and nuts included
• Check torque and safety pin seating after first use

Who is this for? This NBJINGYI 2-5/16" adjustable channel mount coupler is aimed at owners of heavy equipment trailers, flatbeds, and utility haulers who need a rugged, adjustable ball coupler rated for high tongues weights. It suits farmers, contractors, fleet operators, and anyone replacing worn pintle rings with a smoother ball-mount solution. If you tow large loads and want a dependable, low-rattle connection with included hardware for installation, this coupler fits those needs without extra adapters or complex fabrication.
