Heavy Duty Trailer Coupler Lock Zinc Alloy Anti Theft For RV Truck

Designed for RV owners, truck drivers, and first-time trailer owners, this trailer tongue coupler lock secures latch-type couplers on tugs, RVs, trucks, cars, and toolbox latches. It uses a 1/4 inch diameter pin and padlock design that fits latch couplers with a maximum span of 3/4 inch, so you can lock your tow setup without guessing whether it will fit. The lock body is cast from high-strength zinc alloy with a lacquer finish, and the coupler lock carries a galvanized layer for corrosion resistance, helping extend service life through rain and road salt. A 1/4 turn lock activation opens or closes the hook locking pin by turning the flat key 5 to 7 times, giving you a clear, repeatable locking routine at the ramp or storage lot. This anti-theft trailer lock is built for trailer owners who want a visible, sturdy deterrent against coupler tampering. It suits hook-style latch couplers, RV trailers, tugs, trucks, cars, and toolbox latches. It is not designed for couplers with a span above 3/4 inch, not for marine underwater use, and not for coupler styles other than latch-type couplers with the matching span. Specifications:
