It sounds like you have an Unique Functional Product 2-5/16" square coupler which was bought out by Dexter. The MegaHitch Coupler lock part # UF35-946510 is designed to fit the standard sized coupler so it will most likely not be wide enough or tall enough to fit the square coupler according to Ultra-Fab.

I recommend to measure the height and width of your particular square coupler and compare it to the Blaylock EZ Lock Trailer Coupler Lock part # BLTL-33-40D which has a inside width of 4-3/4" and inside height of 3-1/8". The Blaylock is your best bet to fit the square coupler because of it's design as long as the coupler is not too wide or tall to fit.
