Install a Peephole

Make your home safer and more secure by adding a peephole in your exterior doors. You can see who’s there before you open it.

Install a peephole in a door

Many entry doors are fitted with tiny peepholes that don’t always show you who’s there. Strangers can hide slightly out of view, or the distorted shape could appear to be a neighbor but actually be someone else.

Avoid uncertainty by installing a wide-angled viewer. Order from Improvements Catalog or from online sources. It’ll fit any exterior wood, metal or fiberglass door that’s up to 2 in. thick. Following the steps shown in Photos 1 – 3, you can do the job in less than 10 minutes using a drill fitted with a 1-3/4-in.-dia. hole saw.

Our door is fiberglass clad which requires slightly different techniques than wood doors. When installing the unit into wood doors, screw and tighten the viewer body into the prism cover until the plastic spikes on the prism cover bite and lock into the door veneer.
