The Burg Wachter Gate & Railing Post Box is made from powder-coated galvanised steel, designed for secure mounting on fence or gate railings with a rear letter slot. This high-capacity post box features a rear door with key lock access and a vertical post slot on the front covered by a lift-up flap, allowing it to sit neatly between railings and be held in place with two strong heavy-duty clamps. It accepts up to C4 envelopes and comes complete with a mounting bracket for straightforward installation.
