Description
Bulldog 580401 is a chrome-plated, dogbone-style keyed receiver hitch lock for a compatible 2-inch square hitch receiver. The manufacturer specifies a 5/8-inch pin diameter and 3-inch span for standard Class III/IV-style receiver attachments. Its Lifelong-series locking system uses a dual self-locking design and high-security square key; the included dust cap helps protect the lock cylinder from water and road grime. This is one receiver lock, not a trailer coupler lock or a two-piece combination set. No separate retaining clip is needed. Check receiver width, hole size and shank clearance before use.
