Trailer Coupler Lock

This listing is for one coupler lock keyed alike. The reason for a single lock being keyed alike is so you can either match this lock up with another padlock or if in the future you'd like to key another 377KA the same.

You can order as many of these locks as you'd lock and we will make certain they are all keyed alike.

This lock protects unattended trailers and guards against tow-away theft. Fits 1-7/8", 2" & some 2-5/16" couplers. For 2-5/16" couplers we recommend one of the Model #379 locks.
