Description
Bulldog 580406 is a stainless-steel combination towing lock set, not just one hitch pin. The manufacturer identifies the set as a dogbone-style receiver lock supplied with a sleeve for compatible 1-1/4-inch and 2-inch square receivers, plus a trailer-coupler lock. The receiver-lock design features a square-key mechanism, dual self-locking action and a protective dust cap. Confirm both the receiver pin-hole fit and the trailer coupler's lock-hole dimensions before purchase. This combination set is distinct from Bulldog 580405, which supplies the receiver lock without the accompanying coupler lock.
