Many of today's replacement letterboxes for doors are standardised to a large extent and fall within the size range between 10 and 12 inch. When searching for a door letterbox use our filters to define the type of door whether upvc, aluminium, timber or composite and then work down to the individual details. Do check with any replacement upvc letterboxes that the sleeve can fit through the aperture that is already cut through your door, or some diy will be needed!
