How to fit a mortice lock

You will need:
• Drill and Drill Bits ( 19mm),
• Chisel,
• Posidrive screwdriver
• Pencil



Step 1: Position lock body as near to the mid-height of the door
as possible. Place lock body against door edge and mark top and bottom of lock body on door edge, avoiding joints of cross members in the door.












Step 2: Between these two lines mark the central vertical position (dotted line). Along this vertical line drill a series of overlapping holes to the lock depth. In order to drill to the correct depth apply adhesive tape to the drill bit to the measured lock depth (including the forend and face plate).










Step3:With lock body inserted, draw around forend on door edge - remember to add removable faceplate before tracing outline. Remove lock and chisel recess to accommodate lock faceplate. Place lock in door and ensure a good fit with faceplate flush with door edge











Step 4:With lock held against door face ensuring faceplate is flush with door edge and in line with lock recess, mark position of the key hole (and spindle). Drill and cut holes on both sides of the door for the key















Step 5: With faceplate in position secure lock into door with screws provided. Fit escutcheons and/or door handles with spindle cut to suit. Test for easy working operation.









Step 6: With the door open and the bolt in the locked position, close door gently against door frame. Mark positions of bottom of bolt and top of latch bolt.













Step 7: Hold box striker up to door frame, ensuring the box section is in line with previous markings. Draw around box section of box striker on door frame. Along the vertical line.











Step 8: Drill a series of overlapping holes to the box depth. Hold box striker up to frame and draw around edge of box striker. Remove box striker and chisel out so that box striker sits flush in door frame. Secure the box striker using screws in the central or elongated holes only. Test lock for working operation, and adjust position of box striker if required. When aligned correctly, fit the two remaining screws.
