Expert Reply:

The physical difference in terms of appearance between various well-known gooseneck coupler manufacturers is hard to spot because they all are fairly similar. The biggest difference comes with the width of the coupler flange.

The best way to determine which coupler lock is needed, the Blaylock EZ Lock for Bulldog/Stallion/Superior/T.E.M. # BLTL-50 or the EZ Lock for RAM # BLTL-55, is to take a quick measurement on your coupler's flange width.

The EZ Lock # BLTL-50 has a width between the tabs of 4-1/2 inches while the # BLTL-55 is for wider couplers and has a width of 5 inches. You will just want to choose the model that will accommodate the flange width on your existing coupler. I have attached a couple images to assist.

To pick out the right lock you'll just need to measure as mentioned above. I can't be sure what type of coupler flange is used on your Kaufman trailer.
