These standard latch strikes are constructed of steel and come in an antique brass plated finish. They feature an adjustable tab designed to eliminate the door slop and chatter of closed doors, and they're installed with two #8 x 1 inch fasteners included with each package. These latch strikes are used by many to replace most residential interior and exterior door strikes. Adjustment tip: to eliminate the loose rattling of a closed door, remove the strike plate and bend the tab slightly with a pair of pliers, adjusting left to right as necessary.
