What is the Best Trailer Coupler Lock Made by Masterlock

Expert Reply:

Depending on the size and style of your trailer coupler I would recommend the following locks made by Master Lock. The first would be the Master Lock 1-7/8 inch and 2 inch Trailer Coupler Lock, item # 377DAT.

If you have a 2-5/16 inch coupler the Master Lock 2-5/16 inch Trailer Coupler Lock, item # 378DAT, is an excellent lock that fits many styles of trailer couplers.
