The built-in dual locking system is a step up in security and convenience from a standard ball mount because there is no separate hitch pin to mess with – both the adjustment pin and the hitch pin are built right into the hitch. With the best anti-theft system on the market, you can rest assured that your ALBM is locked safely in your receiver, and with the easy access front-facing locks, you don't have to reach up behind your bumper to lock, unlock, or make adjustments. Each ALBM is precision-machined in the Mountain West with the highest quality materials, making it stronger and longer lasting than any other aluminum ball mount. When you buy an ALBM, you are buying the best quality available, built by people who take pride in their work, right here in America.
