A Guide to Identifying Letterboxes

Letterboxes are typically available in 2 standard widths – 10” and 12” and in either standard or slimline height, all of which are designed to accept A4 size letters. To suit a range of door thicknesses letter boxes are available in telescopic sizes – usually 20/40 and 40/80 – which fix together from either side of a door. Screw fixings are located on the internal half of the letterbox.
