发明名称 Bolt lock and lockset adapter assembly
摘要 A mounting plate having three knockouts for three bolt locations of a deadbolt lock is mounted behind a rectangular opening in the edge of a hollow door. A filler plate and a cover plate are provided to cover the unused ones of the knockouts. When no deadbolt lock is installed in the door, the entire filler and cover plates are used to substantially fill the rectangular opening. When a dead bolt is installed in the door, a knockout is removed to leave an opening at the proper location for the bolt to pass through. The deadbolt lock bore drilling is made on the selected centerline either by the distributor or installer. The filler and cover plates are broken along weakened separation lines and appropriate portions thereof are attached to the mounting plate to cover the unused knockout locations. An adjustable backset lockset mounting arrangement is mounted adjacent the rectangular opening to receive and support the lockset in either of two positions. Breakouts in the door are preformed.
