For composite and upvc doors we would recommend using our door letterbox which is supplied as a full kit and contains a tunnel and brushes to reduce drafts and insulate the door. The sleeve inside the letterbox also protects the door from moisture and masks the aperture cutting.
A highly polished finish with a nickel plating applied to solid brass which is salt tested to 480 hours. Similar to a polished chrome finish but with much warmer tones.
Designed to match our other polished nickel front door furniture to create a feature entrance door.
Maximum door thickness: 72mm. Minimum door thickness: 42mm.
