BOLT Coupler Pin Locks

Secure your trailer with BOLT coupler pin locks. They feature Strattec's patented one-key lock technology, which enables the lock to be permanently programmed to your vehicle's ignition key. These waterproof locks fit towing couplers from 1/2 in. to 3 3/8 in. and are also adjustable in increments of 1/8 in. for a snug fit. Locks are designed to slide easily along the stainless steel pin and are engineered with no exposed shackle to further deter theft. BOLT coupler pin locks feature a plate tumbler sidebar to prevent picking and bumping, and their stainless steel lock shutter keeps dirt and moisture out. Why carry extra keys around? You can't beat the convenience and quality of BOLT products! Show Less
