uPVC Door Viewers (20-35mm)

Features Include:

Door Viewers are a great security accessory as no door should be opened without checking who is on the other side!

Spyholes are an ideal security device against bogus callers. 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.

Each spyhole has gone through rigorous testing, and have each been tested to DHF TS002:2009 which covers Corrosion Resistance, Security (Angle of Vision), Visual Clarity, Resistance to Misting Up, Ability to Clear After Misting, Length Adjustment Range and Marking.

With a variety of door viewers you will be able to select the viewer most suitable for their needs and overall home interior and exterior. Whatever their overall door hardware finish is there is a spyhole suitable to match it. In addition in our Door Viewers range we also offer several fantastic door knockers which have a hole specifically designed to fit a door viewer.

Be sure to also check out our door knockers range for more fantastic options which can also have a door viewer fitted. Made with a solid brass body, and comprising of 3 plastic lenses, each spyhole ensures to give crystal clear performance for years of safe, secure use. As standard, each door viewer is salt spray tested for a minimum of 480 hours, and comes with a 5 year inland coating guarantee. Polished brass and polished chrome door viewers come with a PVD head, which helps prevent rust developing in coastal areas. Polished brass, polished chrome, white and black door viewers also come with a FREE privacy cover!

At MAX6 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.

120 Degree Viewer Test

In order to meet Secured by Design specifications a door viewer must have a viewing angle of 120 degrees (60 degrees on either side). To test the angle of vision, the door viewer is fitted to a wooden block with a thickness of 45mm. The block is then fitted onto a protractor which is visible through the door viewer. The tester must look through the viewer and follow a stick, which they are holding, around the protractor until it is only just in sight through the viewer. This point must then be marked and the process is repeated on the other side. The test is conducted in accordance with DHF TS002:2009 standards.

DHF TS 002:2009 Test Report Data:

Corrosion Resistance
Door Viewer was subjected to a neutral salt spray test as detailed in BS EN 1670:2007 for 96 hours (grade 3).

Angle of Vision
The door viewer was mounted, in accordance with the manufacturer’s instructions, to a 45mm thick (+/-1mm) wooden block which, in turn, was mounted perpendicular to a protractor. Whilst looking through the door viewer, a point source of light was moved into view and the angle at which it first appeared (measured from a datum perpendicular to the “door” face) was noted. The test was repeated from the 180° opposite position and the two readings were added together to give an average “viewing angle” for the cone of vision.

Visual Clarity
The door viewer was mounted in a suitable test-rig in which the viewer was held perpendicular to a sheet of text at a distance of 150 mm. Using normal or corrected normal vision, in good light, attempts were made to read text in progressively smaller point sizes and the smallest point size that could be read was noted. (The font used was Arial Black – regular, printed using Microsoft Word).

Resistance to Misting Up
The door viewer was mounted, in accordance with the manufacturer’s instructions, to a 45mm thick (+/-1mm) painted wooden block – representing part of a typical external door to a dwelling. This, in turn, was mounted in a test-rig in which the viewer was held perpendicular to a sheet of text at a distance of 150 mm. Using normal or corrected normal vision, in good light, attempts were then made to read text in progressively reducing font sizes and the smallest point size that could be read was noted. The wooden block was then stood upright in an environmental chamber and subjected to 72 hours of cyclic humidity to BS 3900-F2:1973. Immediately after the humidity test, the readability test was repeated by the same person.

Ability to Clear After Misting Up
Following the humidity test, the door viewer (still in the wooden block) was allowed to dry out for 72 hours at 30° C, after which the readability test was repeated by the same person who carried out the initial test.

Length Adjustment Range
The door viewer was screwed up to its shortest length and the distance between the mounting flanges noted. It was then unscrewed so that there was a full turn of engagement on all threaded connections and the distance between mounting flanges was again noted.

To fit the MAX6MUM SECURITY door 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.

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.

*Skip this step if you are not fitting the door viewer into a door knocker

MAINTENANCE

Gently wipe the door knocker with a moist lint free cloth every month to remove dust particles.
