This trailer lock helps you to protect the trailer or caravan from theft with its locking mechanism that resists picking and prying. This trailer lock is made of a heavy-duty steel shackle and an aluminium alloy body that has been given a yellow powder-coated finish to prevent rust and make it weather resistant. It’s quite simple to lock your trailer. Simply unlock the bar with the key and pull it up, so the ball is placed in the trailer’s hitch and lock it again. Delivery includes one lock and two keys.
