A spring-loaded, double-engagement latch which locks through the pintle ring for increased strength and reliability. Both an automatic rust-proof latch lock and a manual safety pin insure safe hookups. Quick conversion from pintle hitch to ball hitch to clevis hitch without the need for tools. Forged stainless steel shank with 1-7/8", 2", and 2-5/16" interchangable stainless steel coupler balls. Latch self-parks so it cannot interfere with the coupler during hookup and towing with ball couplers. Gross trailer weight ratings to 25,000 pounds.
