Excellent lock

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.
