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.
● Designed to match our other black front door furniture to create a feature entrance door.
● Maximum door thickness: 72mm.
Minimum door thickness: 42mm.
● Supplied with matching SS bolt through fixings.
