Meet the Proven Locks Model S175, a heavy-duty trailer hitch lock designed for select 2-5/16-inch couplers and compatible 2-inch models. Built in the USA, the lock blends rugged materials with thoughtful security features to guard your trailer and gear whether parked at a marina, resting in a driveway, or during long road trips.
Durable construction you can feel
The lock body uses alloy steel with a black powder-coated exterior that resists scratches and weather wear. The central engagement pin is machined from solid stainless steel, delivering dependable engagement every time you latch it onto the coupler. The overall design prioritizes robustness for everyday use and challenging environments.
Security features that matter
