E-Z Latch ball coupler is an exclusive, new coupler design by Demco. This patent pending coupler latches when lowered over its appropriate sized hitch ball. It's offered in both 2- and 2 5/16-in. ball coupler sizes. Mounting configurations include: weld-on and bolt-on for 3" tongue tube, A-frame weld-on, and bolt-on adjustable height channel mounts. The E-Z Latch feature and the enhanced weight rating, make these couplers an excellent choice when designing to build or when replacing an existing ball coupler.
