  • 1 A door viewer allows visual identification of callers without the need to open the door.
  • 2 Mark on the door where you would like to place your viewer. Ideally it should be located at the centre of the door at eye level.
  • 3 Before drilling always ensure that you’re using the appropriate drill bit by checking the instructions on the pack. Drill a hole through where you have marked using the correct size drill bit.
  • 4 Hold the drill perpendicular to the door and start drilling at a slow speed using a small amount of pressure. Top Tip: To avoid splintering the exterior veneer of the door, stop and check your progress so you will know when the pilot tip first emerges.
  • 5 When the tip of the drill bit first emerges, stop the drill and finish the hole by boring from the other side. Use a wedge to help the opened door steady.
  • 6 Sand the edges of the hole for a smooth finish.
  • 7 Unscrew the two parts of the door viewer and insert the lens through the door from the outside.
  • 8 Insert the barrel from the inside of the door and while holding the lens, screw the barrel until tight to complete the job (use a flat-head screwdriver if necessary).
