C.T.Johnson RH3 Deadbolt Hitch Pin Lock for 2" Class III/IV Receivers - Carbon Steel or Stainless Steel

The C.T.Johnson RH3 Deadbolt Hitch Pin Lock secures any 2 inch Class III or Class IV receiver against theft with a one piece machined 5/8 inch pin and a patented screw-and-lock deadbolt mechanism. Unlike a simple padlock through a hole, the RH3's threaded connection tightens down as it locks, eliminating hitch rattle and creating a rugged, pick-resistant joint that will not false lock. A reversible automotive-style key lets you lock and unlock with either side facing up, even with gloves on, and a weatherproof cylinder with a protective rubber keyway cover keeps grit and moisture out of the mechanism. Choose the original double chrome plated carbon steel RH3 for everyday towing, or step up to the RH3-SS for full stainless steel construction and maximum resistance to rust in coastal, marine, and heavy road-salt environments.

Sizes & Options

Both versions of the RH3 use the identical 5/8 inch pin and fit the same 2 inch Class III/IV receivers, so the choice comes down to material. The standard RH3 is carbon steel with double chrome plating, a durable and corrosion resistant finish suited to most towing setups. The RH3-SS is machined from stainless steel throughout, making it the better pick for boat trailers, coastal climates, and any application with frequent exposure to saltwater or road salt where maximum long-term corrosion resistance matters most.
