Carlisle Brass Door Viewers

Carlisle Brass Door Viewers – practical security and elegant design

Carlisle Brass Door Viewers (also known as peepholes) offer a safe and discreet way to see who’s outside before opening your door. Perfect for both homes and commercial buildings, these durable optical lenses come in finishes such as Matt Black, Satin Brass, Polished Brass, Polished Chrome, Satin Stainless Steel and Polished Stainless Steel — making them easy to match with your other door hardware.

What are door viewers?

A door viewer is a compact, wide-angle optical lens that fits neatly through the door at eye level. From the inside, you can look through to view visitors clearly, even in narrow hallways. Each unit typically includes a lens, a barrel, and a privacy cover for extra discretion. Simple to install, they’re a subtle but essential part of front door security.

Why use a Carlisle Brass door viewer?

  • Feel secure – Identify who’s at your door before opening it.
  • Enjoy privacy – Check outside without being seen.
  • Easy to install – No wiring, no maintenance, just peace of mind.
  • Ideal for all doors – Choose models suitable for homes, flats, hotels, schools, care homes and offices.

Choosing the right door viewer

  • Viewing angle – 180° or 200° wide-angle lenses give clear visibility of entrances and corridors.
  • Door thickness – Use extension sleeves for thicker timber or fire doors.
  • Finish – Match to handles, letter plates, and other front door fittings for a coordinated look.
