Review on 🔒 CZC AUTO Black Trailer Hitch Coupler Lock - 1/4" Diameter, 3/4" Span - Tow Boat RV Truck Car's Security (1 Pack, Black) by Brian Krump

This lock is a bit harder to get on and off than the ones I've had before, but it will be extremely difficult for a thief to pick; maybe even impossible. The wrench acts like a screwdriver and turns the locking pin into a threaded socket. There is no place for bolt cutters to get at the pin. Don't lose your key. , Addendum to my review: After a few months of use, the key is difficult to insert. I was afraid of getting my trailer. I saw another review with the same problem. If I can unlock it again, I don't think it's advisable to use it again.
