The Dual Pack containing two MAXTRAX MAXLOX 30mm heavy duty Stainless Steel padlocks with silicone covers, is designed to protect and also secure your MAXTRAX 4WD Recovery Tracks from potential thieves when theyre mounted on any of our MAXTRAX Mounting Pins. Simply feed the padlock shank through the padlock hole in the shaft of a mounting pin and close the padlock. When travelling, we recommend securing your MAXTRAX (when mounted on MAXTRAX Mounting Pins) with this Padlock, and ensuring that all of the pins are turned to the lock position.
