Depending upon your door, frame or wall thickness you may need an extension piece!

Door viewers (spyholes) are a great security accessory for your customers, 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. Providing your customers with this important information will help them learn to better protect their homes and keep intruders out.

Offering your customers a variety means not only presenting them with great door security hardware but the necessary accessories to make them fit perfectly. The great Door Viewer Extensions are suitable for 14 mm Barrel Door Viewers and provides up to 55 mm added length to fit thicker doors. By increasing the overall length of the door viewer you can easily fit it onto a variety of different thickness doors.

In order to determine what size extension will be necessary measure the thickness of the door, frame, or wall where the door viewer will be fitted!

testing icon

At UAP we are constantly striving to improve on the products we already supply as well as develop new, pioneering ranges and practical product solutions.

With an in house testing centre and product developer, each stage of the development process is thorough, from the initial design right down to the final product. In house 3D printing technology allows for further and more precise advancement of our products which are then expertly manufactured and put through stringent testing conditions using in house test equipment – ensuring all products are designed to the highest standards:

Salt Spray Test

This machine tests the corrosion resistance of the door viewers. The salt spray cabinet produces a corrosive environment, by releasing a dense saline fog into the chamber which the products are exposed to. This creates an accelerated corrosion of the product and allows us to test how well the door viewer would stand up in harsher environments.

The door viewers are tested for differing lengths of time depending on the standard requirements; 480 hours for brass, zamak and aluminium based door viewers where we offer a 5 year inland coating guarantee, and in the case of stainless steel Nanocoast door viewers, we test for 2,000 hours where we offer a LIFETIME coating guarantee anywhere in the country, as the door viewers will not pit or rust.

All Weather Machine

When placed in the all-weather machine, the door viewers are subjected to conditions including high UV exposure using a Xenon Arc Lamp which will accelerate UV degradation and measure how well a door viewer can last in extreme conditions.

Other conditions such as rain and extreme heat can be generated by the machine to expose door viewers to all kinds of environments. This allows us to continually improve the door viewers and make them so they last longer in all kinds of different environments.
