Built from high-strength steel with a black electrophoretic finish and a zinc-alloy tubular core, the lock is engineered to resist rust and everyday wear while fitting common latch-style couplers. Two keyed-alike pins are included, and a watertight rubber cap keeps debris and moisture out of the mechanism.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this coupler lock fit my trailer?\u003c\/h3\u003e\n\n\u003cp\u003eThe CZC AUTO pin is sized for latch-type couplers that accept a 1\/4\" diameter locking pin and need an effective span of about 7\/8\" (pin head length ~0.97\", bottom ~0.95\"). Always measure your coupler pin hole and clearance before ordering to ensure compatibility. Incorrect sizing will prevent the lock from seating or functioning properly.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eNominal pin diameter: 1\/4\" (0.25 in)\u003c\/li\u003e\n  \u003cli\u003eEffective span\/length: 7\/8\"\u003c\/li\u003e\n  \u003cli\u003eHead length: 0.97\"; bottom length: 0.95\"\u003c\/li\u003e\n  \u003cli\u003eBest for latch-style couplers on boats, trailers, RVs, and trucks\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat materials and construction protect the lock from weather and tampering?\u003c\/h3\u003e\n\n\u003cp\u003eThis locking pin combines a high-strength steel shaft with an electrophoretic black coating to slow corrosion and surface wear. The locking core is zinc alloy tubular construction for sturdiness, and a rubber dust cap seals the keyway against rain, snow, ice and road grime.
