Frozen tumblers? Seized plug? No Problem! Peterson's Adams-Rite Latch Trip Wire goes right through the key-way to retract the latch with the greatest of ease. One turn duplicates the action of the cylinder tailpiece, making the lock's design work for you. Made from the highest-grade steel available, this wire is thin enough to fit through the tightest key-way and strong enough to hold its shape, trip after trip.
