Intuitive and Deterrent Lock
Having used other trailer coupling locks before, this was the easiest to use. All in one piece no dismantling. Turn the key, slide it out, fit it under the coupling and lock. Very intuitive. Red colour makes it prominent from afar, good deterrent. Highly recommended. Ordered another one for a friend for his caravan.

It sucks
We purchased in 2019 maybe used four times and I asked my husband why we were not using it to lock the boat trailer… he said “it constantly gets James stuck and I have to fiddle with it for five or more minutes to get it opened.” Well, yesterday I put it on the boat hitch eek he was frustrated with me when it took us 23 minutes to get it off hitch he was walking back with his iron cutter when it finally opened after me working on it to release after a long time! Worthless and doesn’t work smooth.

Fit both 2” and 2 5/16 trailer hitches
Installed easily and has very good reviews from several websites. I bought two of them. One for my car hauler with a 2” receiver and my travel trailer with a 2 5/16” receiver
