Our take on the Demco Adjustable Coupler 2-5/16" 14040-81 21,000 lb Capacity Black

The Demco 14040-81 is an adjustable trailer coupler rated for 21,000 lb GVWR when bolted on with four 5/8-inch Grade 5 bolts. It fits 2-5/16-inch hitch balls and uses Demco's eZ-Latch mechanism, which latches without a separate safety pin. A black powder coat survived 500 hours of salt spray testing, and a security hole lets you add a lock. It suits heavy flatbed, equipment and dump trailers where a fixed coupler would be awkward to line up; the trade-off is that it needs proper bolt installation and a lock is sold separately.
