Review on 🔑 Sumnacon 220-Degree Safety Door Viewer - Solid Brass Peephole with Privacy Cover for Doors 1-3/8" to 2-1/6" - Durable Viewer for Home, Office, Hotel (2 Pcs, Black) by Daniel Hicks

It was perfect for my doors. Very easy to install. The product appears to be of good quality. The 220º viewing angle is more than a normal peephole, so you can see everything from every angle behind the door. A question arises: how to install it? There are no instructions included with the product, but based on my review, you really don't need them. First, decide where you want to place the peephole on the door (a comfortable height for all household members who will be using it, centered horizontally on the door, and aesthetically pleasing). Mark the position with a pencil once you have decided. Using a 1/8" drill bit, drill a pilot hole that goes through the width of your door. Then take a 5/8" drill bit to drill through each side of the door through the pilot hole. Currently, due to chuck limitations, most drills will not accept drill bits larger than 3/8 inch. There are many drills you can find for this. This is the one I also bought from Revain to achieve this. Here's the one I bought: Togu DB-02 5/8" (16mm) HSS steel drill bit (Revain ID: B01K45O8FI). / 8" bit on EACH side of the door. This is to ensure the drill hole is clean on each side and to prevent splitting of wood or metal. Next, blow the debris out of the drill hole, insert the peep hole and tighten the screws. idea), you can seal it up a little decision to buy this peephole. Thank you for reading!
