Expert Reply:

The Demco EZ Latch Couplers like the part # DM16680-52 have lips on them which is why the AMPLock Trailer Coupler Lock for 2-5/16" Ball Couplers w/o Lip # AMP34FR is not going to work as it's designed for couplers without a lip.

You'd want something that was designed for lips like the part # e98894 instead. This fits with lips and also with a 2-5/16 inch ball fit.
