Abstract
A method and apparatus for marking positions for burglar alarm sensor elements on a door, the door attached to a frame having a header including comprising the steps of providing a positioning member with a longitudinal, and punch point attached to the positioning member, the punch point being aligned with the longitudinal centerline of the positioning member; at least partially opening the door; placing the positioning member in a hole in the header and closing the door; while the door is closed causing the positioning member to make a mark on the top of the door; and opening the door and removing the positioning member from the hole in the header; and causing an opening to be made in the door at the location of the mark.
Claims8
A method of installing a latch or door plate on a door frame attached to a door, comprising the steps of:
- (a) providing a positioning member, the positioning member having a longitudinal centerline, a bore which passes through the longitudinal centerline and a marking point, the marking point being aligned with the longitudinal centerline of the positioning member, and the positioning member including a pair of longitudinal grooves and lower open areas, the longitudinal grooves having a first width and the lower open areas having a second width, the second width being larger than the first width, and a flexible member having first and second ends and passing the flexible member through the bore such that the flexible member is at least partly contained in the longitudinal grooves;
- (b) partially opening the door;
- (c) placing the positioning member in a hole in the door;
- (d) while the positioning member is in the hole, closing the door in the door frame, and while the door is closed in the door frame, applying force on the flexible member by pulling on the flexible member, which force is transferred to the bore and then to the positioning member to cause the marking point of the positioning member to make a positioning mark on the frame, and continuing to apply force on the flexible member by pulling while at least partially opening the door causing the marking point of the positioning member to enlarge the positioning mark on the frame;
- (e) after step “d”, opening the door and removing the positioning member from the hole in the door;
- and
- (f) after step “d”, using the mark made in step “d” as a basis for installing the latch or door plate on the frame.
