Full Long Description
This 2" Straight Tongue Trailer Coupler with 3" single channel is an upgraded heavy medium-duty towing accessory, specially designed for 3" large-size square straight trailer tongues. It perfectly matches standard 2" trailer balls and is widely applicable for heavy utility trailers, large boat trailers and medium heavy cargo trailers with 3" square tongues.
The coupler body is made of reinforced thick heavy-gauge steel, with improved structural strength and pressure resistance.

It can maintain stable locking state on bumpy roads and during high-speed towing. Matched with high-strength safety pin and anti-lost chain, it completely eliminates the risk of accidental uncoupling under heavy load.
Standard pre-drilled mounting holes are compatible with 3" square tube trailer tongue installation standards. Fast bolt-on installation without welding or cutting, convenient for trailer maintenance replacement and new equipment assembly.
