Weight Distributing Head (WDH) adaptor plates Silver 7/8″ standard shank size suits Auto Coupler

These adaptor plates are used when hooking up a drop on coupling onto a Weight distributing head. It replicates the surface of a normal tow tongue.

This gives the tapered pin a nice flat even area for it to seat, and for the coupling to clamp down onto.

Towpin and weight distributing head are for illustrative purposes only.
