Product Information
Fitting Instructions

Door viewers (sypholes) are a great security accessory for your home, as no door should be opened without first checking who is on the other side. Door security is essential to ensuring a home is safe and once quality locks have been fitted it’s key to have a door viewer. Many homeowners overlook the importance of really seeing who is on the other side of the door and essentially this can actually be the best way to prevent unwanted guests, break-ins, and scams. 

These door viewers are designed to be fitted with standard door knockers, and are designed for wooden and composite doors with thicknesses between 38-63mm.

Door Viewer Features:

1 Made with a solid brass body
2 Comprises of 3 plastic lenses
3 Ensured to give crystal clear performance for years of safe, secure use
4 Free privacy cover included
5 Comes in 6 different finishes to match your door knocker
6 Additional extensions are available if you need to make your viewer even longer
7 Lifetime coating guarantee anywhere in the country

Live Near The Coast?

Products pitting and rusting near the coast is a very common problem due to the salt in the air

If you live near the coast (defined as within 25 miles away) or within 5 miles of a heavily populated industrial area, it is a very common problem for door hardware to pit and rust (usually within 6 months of it being fitted). The high concentration of salt and chemicals in the air corrodes most metals including brass, zinc, zamak, nickel and more.

UAP have developed a range of products developed specifically for the coast - called Nanocoast. These products are made from 316 grade stainless steel, and have been salt spray tested to ASTM B117:2005 for 2000+ hours (the industry standard is 480 hours).

UAP are so confident with the quality of their Nanocoast products that they offer a LIFETIME coating guarantee, meaning that they will not pit or rust no matter where you put them in the country!

Fitting Instructions

Fitting Your Door Viewer

To fit the viewer you will need a tape measure, pencil, drill and 12mm bit:

1. Use a tape measure and pencil to make a mark on the door where you want the viewer to go. If you are also fitting a door knocker, mark the holes for the knocker’s mounting bolts by measuring the distance from the door viewer hole to the bolt holes and translating this to your door. Drill through the bolt hole marks for the door knocker.

2. Drill a pilot hole for the door viewer then change the drill bit to 12mm and drill through the door.

3. Fit the door knocker to the door (skip this step if you are not fitting the door viewer into a door knocker.)

4. Unscrew the two halves of the door viewer, then insert the half with the lens through the outside of the door.

5. Insert the half with the privacy cover into the inside of the door and screw the two halves together by hand.

Please Note – The door viewer length can be altered by screwing and unscrewing the 2 halves to the desired length. DO NOT cut down the door viewer to your required size.

Cleaning Your Door Viewer

Every month, wipe the door viewer over with a moist cloth and remove any dust particles that may have accumulated, and finish off by wiping the door viewer with a lint free cloth.
