The heavy duty front and rear castings of the Lettasafe post boxes are made from solid thick aluminium. The inner sleeve is made from strong zintec coated steel and when these mail boxes are built into a brick wall or brick pier your letter box is extremely vandal resistant. Your postbox can be made even more secure with the optional anti theft restrictor plate.
The mailbox shown is a sectional view of a Bloomsbury rear retrieval mailbox fitted through a brick pier.More details are available by clicking on the letterbox image.
