Gatehouse W3-1 Rear Access Letterbox with Trim for Gates

The Gatehouse W3-1 Rear Access Letterbox with Trim for Gates and Fences is a secure, high-capacity post box designed for mounting through gates, fences, and boundary entrances. As part of the bestselling W3 range, the W3-1 offers a larger collection box than the standard W3, making it ideal for properties that receive regular or higher volumes of mail. This trimmed version is supplied with both front and rear fitting trims, giving a clean and finished appearance around any cut edge in a gate or fence. Mail is posted through the front chute and retrieved securely from the rear, making the W3-1 a practical solution for gated properties, driveways, fence lines, and commercial entrances. Made from galvanised steel and thermally powder coated for enhanced rust resistance, the W3-1 is built for long-term external use. The mail chute has a depth of 25mm. If you require a larger mail chute, the W3-2 with Trim may be a more suitable option. The W3-1 is available in Black and Dark Grey RAL 7016. The dark grey powder-coated finish has a smooth matt appearance, while the black powder coating has a slightly textured gloss finish. A stainless steel front version is also available. Supplied with a secure cylinder lock from Euro-Locks Lowe & Fletcher and 2 keys, the Gatehouse W3-1 with Trim keeps your mail stored safely and securely.
