Make your back seat into a safe using the DU-HA lock kit! Now that you have a place to put all your stuff, you can lock it up. The DU-HA GM Lock Kit locks the rear seat bracket so unwanted visitors cannot lift up the back seat and gain access to the gear stored in your DU-HA. Covered solid body padlock features a 1-9/16 in (40mm) wide black vinyl covered body for scratch and corrosion resistance. The 1/4 in (6mm) diameter shackle is 13/16 in (21mm) long and made of hardened steel, offering extra resistance to cutting and sawing. The 4-pin cylinder helps prevent picking and the dual locking levers provide resistance against prying and hammering. Lock Material: Chrome steel, vinyl, and corrosive resistant materials.
