The STS 4008 door viewer is fire-rated* and has a massive viewing angle of 200°. Our viewer is specifically designed to maximise your security and minimise damage to the face of the door during fitting. The viewer is fully-adjustable and can be fitted to doors ranging between 36mm and 60mm thick. It comes in either a gold or chrome finish and is fitted with ceramic glass which withstands massive heat fluctuations without shattering. Designed to minimise potential damage to timber doors during installation, the rear flange has a significantly greater diameter to prevent the viewer pulling through the door. The recessed drive slots prevent the tightening tool slipping and gouging the door face.
