I use this on both a 1 7/8 inch and a 2-inch kayak trailer that I keep in a storage unit. It's nice to have this extra measure of security.

I bought this to replace a nearly identical lock after losing the keys to it. This newer version is extremely flimsy. It could easily be broken with a firm hit with a 4lb mallet. It's not solid like the previous one. The metal is very thin. The previous one weight maybe 3lbs, this might be a pound. I'm still going to use it since I believe having it on the trailer will deter theft and it looks much more sturdy than it actually is. But if thieves knew these were garbage, we'd all be in trouble.

It looks like a good lock but I’m sure you could break it off with a crow bar !

Have a large tongue for the RV - ball would not come out and the lock was to small for my tongue.
