Measure about 80 inches up the wall from the floor. Mark the point with a pencil. This distance assures a sufficient length for the cuckoo clock's weight chains to hang freely.
Drill a hole the same diameter as the expansion fastener.
Insert the expansion fastener into the hole. Lightly tap the fastener with a hammer until the fastener head is even with the surface of the wall.
Install the fastener screw and turn it slowly clockwise with a screwdriver. Stop turning when the fastener pulls against the wall.
Turn the screw counterclockwise until the head of the screw is approximately one-quarter inch from the wall surface.
Hang the cuckoo clock on the fastener screw.
