The J-Lock, load lock rack is a lockable, anti-theft storage and security system that easily mounts nearly anywhere on your truck to safeguard your load locks when not in use. Four styles ensure that there’s a J-Lock especially suitable for your rig. J-Locks are manufactured in either 2 or 4 bay versions to fit your specific need. Each load lock is securely cradled to ensure no movement — either side to side or up and down. J-Locks secure both 1 1/2″ or 1 5/8″ bars. J-Locks also accommodate 2″ x 4″ or 4″ X 4″ pads.
