The RWM Adjustable Floor Lock eliminates the need to buy multiple locks for different carts. This lock can be applied to carts with wheels 6″ to 8″ in diameter. In addition to a foot-activated locking and unlocking mechanism, a rubber-bottom pad secures floor grip to lock the cart in place. This bottom pad rotates to allow the height of the floor lock to adjust up to 2-3/4″. A zinc-plated coating protects from corrosion. By design, the adjustable floor lock is ideal for use on carts with different caster heights and stabilizes carts for loading and unloading by locking the cart while holding all wheels in position.
