"This 24"" aluminum heavy-duty ramp attaching bracket is designed to secure pin-end loading ramps directly to a dock surface or trailer deck for optimal safety and security. By pinning loading ramp tubes in the skid seat channel, the ramps stay fixed to a trailer deck or loading dock and will not slip off while loading heavy equipment. Pull-pin style attachment bracket enable fast ramp setup and the ability to quickly swap between loading ramp sizes on the go."
