The Power Locker Equipment Tie Down secures wheeled equipment in just seconds. It is the only complete wheel lock system on the market that meets all state and federal laws in one box. It installs securely to the deck of most open or closed trailers. Once in place, simply drive onto the pivoting shoe and it automatically locks into place. To remove the equipment, simply pull the swing pin and drive off. The lock can be completely removed from the floor bracket with a single pin in seconds, freeing the trailer space for other hauling needs. Power Lock comes in four sizes to fit most equipment. All Power Lockers are also interchangeable ? the front and rear mounting brackets fit all Power Locker sizes. A padlock can be used for added security, though the Power Locker is not primarily an anti-theft device.
