The backs of most analog clocks feature two specially designed clock-lock hangers spaced at precise distances, one on the top and the other on the bottom. The clock-lock feature prevents accidental removal if the clock is bumped and it may reduce theft by requiring a particular combination of moves to remove the clock. To avoid the clock-lock feature, use finishing nails with no heads angled at 45 degrees into the wall in place of headed screws.
Verify the installation requirements are met.
Drill holes for the screw anchors at the spacing listed in the following table. If two screws are being used to secure the clock to the wall using the clock-lock mount, the distance between the screws is precisely the same as the hole spacing specified below.
Use a screwdriver to insert and tighten each screw, leaving the top of the screw head 3/8 in. (0.9 cm) out from the wall.
Apply power to the clock.
Hold the clock with the face down and align the clock-lock hanger with the bottom screw.
Tilt the clock face to vertical and position the clock with the screw heads in the opening of the clock-lock hanger.
Slide the clock down over the screw heads to latch it into place.
