Abstract:
An exemplary deadbolt includes a pair of rollers positioned on opposing sides of an axial centerline of the deadbolt. The deadbolt may include chamfers or tapered surfaces extending from side surfaces of the deadbolt toward a face of the deadbolt. The rollers may extend beyond the face, one of the side surfaces, and/or one of the tapered surfaces. As the bolt moves from a retracted position to an extended position, one of the rollers may engage an edge of an opening in a strike plate, for example when the deadbolt is misaligned with the strike plate opening. As the rollers engage the edge, the deadbolt may be urged to a more aligned position.
