Peace of mind when owning a camper or trailer.
Very solid travel trailer tongue lock. Adjustable and easy to use and absolutely impossible to get off without the key. Definitely gives me an added relief knowing our camper is secure when we're not home. Fully coated with a durable scratch resistant coating to prevent rust and looks really good.

Works as it should as a deterent
Works like a charm! I see no reason not to get one.Yes, if someone really wants your trailer, they will get it. Security items like this are just to "harden the target"...to make your trailer more difficult to steal than the guy who has no lock. If they can just hook up and go, then they probably will...if they have to take the time and risk to bash a lock like this off with a hammer, it's less likely they will risk it.And to those who are thieves, may the flees of a thousand camels infest your underwear...and the underwear of all who call you friend!

Does it fit
Easy to install and remove. I use it on the 2inch and the bigger 2 and 5/8 hitch. Gives you a piece of mind when leaving the trailer
