C.T.Johnson Trailer Coupler Lock RC3 for 2 Inch Coupler Opening

The C.T.Johnson RC3 is a conventional trailer coupler lock built to secure a trailer coupler with a 2 inch opening. It is a machined lock designed to fit directly onto the coupler to help deter unauthorized hitching and theft while the trailer is parked or in storage. The compact, machined construction is sized to work with standard 2 inch coupler openings found on many boat, utility, and cargo trailers.

At 0.5 pounds, the RC3 is lightweight enough to store in a tow vehicle or trailer tongue box and take along whenever the trailer is disconnected. Its dimensions of 6.6 x 1.8 x 1.5 inches keep it compact for easy handling and storage. The RC3 is intended as a straightforward, no-frills security accessory for trailer owners who want a dedicated lock for the coupler itself rather than relying on a generic padlock alone.
