BulletProof Hitches Extreme Duty 2-5/16" Channel Mount Coupler

The BulletProof Hitches Extreme Duty 2-5/16" Channel Mount Coupler is a Class 5 trailer coupler built for heavy commercial and industrial towing, rated for up to 36,000 lbs. maximum towing capacity and 6,000 lbs. maximum tongue weight. It mounts to a standard 3" channel using three 5/8" bolts and accepts any standard 2-5/16" hitch ball.

Fully Welded Steel Construction

The Extreme Duty Channel Mount Coupler is fabricated from fully welded steel throughout, with no cast components and no press-fit joints. That construction method matters in high-load towing: welds distribute stress across the joint rather than concentrating it at a single point, which is where couplers fail under repeated shock loading. For daily commercial use on dump trailers, equipment haulers, and heavy flatbeds, that margin of structural integrity is the difference between a coupler that lasts a season and one that lasts a decade.

Powder-Coat Finish with Attached Tether and Locking Pin

BulletProof Hitches applies a powder-coat finish to the coupler for corrosion resistance in wet, muddy, and road-salt environments. The tether and locking pin are attached to the coupler body rather than loose, so they cannot be misplaced between uses. That captive design is a practical advantage when the coupler is being connected and disconnected repeatedly on a job site. The coupler is also compatible with the BulletProof Hitches Security Bolt for anti-theft applications.

Specifications

Who This Is For and Isn't

This coupler suits operators running heavy trailers (equipment haulers, dump trailers, flatbeds, or commercial utility trailers) that require a Class 5 rated connection and mount to a standard 3" channel tongue. It is appropriate for any application using a standard 2-5/16" hitch ball.

The Extreme Duty Channel Mount Coupler does not include the three 5/8"-11 grade-8 bolts, three 5/8"-11 grade-8 locknuts, or six 5/8" flat washers required for installation; those must be sourced separately. It is not a vehicle receiver-hitch accessory and does not mount to a standard 2" or 2-1/2" receiver tube.

Common Questions

What mounting hardware is required, and is it included?

The Extreme Duty Channel Mount Coupler requires three 5/8"-11 × 5" grade-8 bolts, three 5/8"-11 grade-8 locknuts, and six 5/8" flat washers for installation. None of this hardware is included with the coupler and must be sourced separately before installation.

What is the towing capacity of this coupler?

The BulletProof Hitches Extreme Duty Channel Mount Coupler is rated for a maximum towing capacity of 36,000 lbs. and a maximum tongue weight of 6,000 lbs., placing it in the Class 5 category for heavy-duty and commercial towing applications.

What channel size does this coupler fit?

The Extreme Duty Channel Mount Coupler is designed to fit a standard 3" channel tongue, secured with three 5/8" mounting bolts. It is not designed for receiver-tube or pintle-hook mounting configurations.

Is the locking pin captive, or can it be removed and lost?

The tether and locking pin on the Extreme Duty Channel Mount Coupler are attached directly to the coupler body, keeping them captive so they cannot be misplaced between uses. That design is particularly useful for operators who connect and disconnect the coupler frequently in the field.
