The C.T. Johnson RC4 Dead Bolt Surge Coupler Lock provides robust security for trailers equipped with 2-1/2 inch surge brake style couplers. This heavy-duty lock features a flush-mount design that sits smoothly within the coupler opening, preventing unauthorized hitching and protecting your trailer from theft.

• Flush lock design provides a low-profile, tamper-resistant installation
• Durable nickel chrome finish resists corrosion and weathering
