Excellent lock

Doug December 8, 2025

This is the best type of hitch lock I have been able to find. It fits securely in the ball socket of the trailer hitch. The locking mechanism fits snugly to the outside of the hitch socket. The construction is robust. Unauthorized removal without the key would be very difficult. This Master Lock trailer hitch lock provides me peace of mind. My nice trailer is secure.

Accommodates multiple hitch ball sizes.

Randy November 21, 2021

The locking mechanism slides to accommodate multiple ball size so you need to ensure the lock is installed snugly before locking. Seems to be good quality and durable but only have used a couple of times.
