I'm very pleased with my new trailer lock It is very simple to install, light weight and affordable. It also carries the Master Lock name that we've all come to trust for security!

Go to plan B

TLR October 17, 2025

Plan “A” was to use this lock on a 2 5/16” ball size travel trailer tongue but the lock width is too narrow, so I went to plan “B” and used the lock on a 2” Bulldog utility trailer. No problem!

Great deal!

Myra December 11, 2025

Works perfectly! It's just a little bulky, but I guess it needs to be so it is harder for someone to cut through it and steal my trailer. It is very sturdy and well made. A value purchase.

Great Lock For Price

Frank August 9, 2020

Nice. Adjustable, fits my cargo trailer tight when locked. Just light any lock, it is for deterrence only. NO LOCK IS 100% THEFT PROOF. If someone wants it they will get it. This lock is only 1 of 4 steps I use to protect my trailer.

OK but

Scott September 23, 2025

The lock works great, however, I have two trailers. It works great on one but the other one is a bulldog hitch and the lock isn't deep enough to get into the opening for the bulldog hitch

Good lock overall

Doug July 11, 2025

Well made. Replaced a U-shaped lock. The U-Shaped lock was from a major brand but the key/cylinder was poor quality. I was worried it would leave me stranded if it jammed (which it constantly threatened to do). The master lock has a smooth worked lock mechanism that I trust. I have an odd coupler so the fit of the Master lock is not good as I would like but I am satisfied overall. Good lock in this price range.
