“I have my airstream parked in a fenced storage in a great neighborhood and someone tried to steal it. This lock did not budge and did not break! Just bought another to replace. Customer for life!”

“Very heavy duty. Trust my boat with it. Fits perfectly. Also chained and locked my boat to a concert pillar in the ground.”

“I’ve recently purchased my first travel trailer and when I got it home my first thought was “man this would be really easy to steal”.Not anymore!I’ve had zero worries about this trailer being stolen now that this beefy lock is installed.It’s spendy but the piece of mind is so worth the money. Highly recommend!

“This is a very solid lock made from solid heavy steel. It easily installs and uninstalls with the turn of a key. The lock is in two pieces, a ball and coupler. When the two are locked together the unit becomes very solid. To make sure you get the right size, it's important to follow the measurement guidelines on the amplock web page. I'm not sure how antitheft the lock is, but it would take some very sharp tools and some time to remove from the trailer. You definitely get your monies worth with this lock.”
