    Well made and I like the cover over the key hole.

    Worked well for me. I have a 2 part drop hitch on my truck and wanted to lock it down so I don’t have to keep taking it off and on to keep it from getting swiped. Cap over keyhole is good idea too.

    Like the sliding lock protector. Better than the ones with plastic caps which over time shrink/tear.

    I have actually bought 3 of these things, for different trailer hitch setups. They are nice looking chrome, but don’t leave them out all the time or they will rust. The lock part clicks on without needing the key, and the keyhole faces you, making it easy to remove.

    Needed to replace the pins for my trailer ball hook ups on my trucks. These work great and easier to lock and unlock too.

    Unlocks easy , locks without key with just pushing on , could use better design to seal out moisture, overall ok Mines a 5/8″ dia.

    My trailer hitch was stolen by meth-heads and sold for scrap metal on numerous occasions. I finally bought this lock and now I can sleep at night knowing that some random person can’t just take my hitch and sell it on the black market.

    I have had the other lock pin but you couldn’t get the key in after while the lock was rusted up. This one has a cover for the lock hopefully this fixes the issues I had before.
