  • Reversible mortise lock
    Patent number: 8261584
    Abstract: The reversible mortise lock of the present invention can be installed on either the left or right side edges of a door opposite the door hinges. The lock includes a housing with a live bolt pivotally and slidably mounted in the housing. The live bolt slides between an extended position beyond the housing and a fully retracted position within the housing. When fully retracted, the live bolt can be rotated 180° so that the beveled face of the live bolt can be reversed. A finger pivotally mounted within the housing blocks full retraction of the live bolt when the mortise lock is installed in the door.
