How to Install a Door Viewer

Share |

Woodie's DIY will show you how to install a door viewer. It's a simple security measure that's easy to install.

How to do it

Step 1

A door viewer allows visual identification of callers without the need to open the door.

Step 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.

Step 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.

Step 4

Hold the drill perpendicular to the door and start drilling at a slow speed using a small amount of pressure.

To avoid splintering the exterior veneer of the door, stop and check your progress so you will know when the pilot tip first emerges.

Step 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 keep the opened door steady.

Step 6

Sand the edges of the hole for a smooth finish.

Step 7

Unscrew the two parts of the door viewer and insert the lens through the door from the outside.

Step 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).
