The W3 is our best selling range of letterboxes. The W3-1 has a larger collection box than the W3. This rear access letterbox is the perfect solution for mounting through your gate or fence. The trim provides a clean and finished look to any edge cut in a gate or fence. It’s designed to hold lots of mail, safely and securely. It comes with 2 keys. The mail chute on this rear access letterbox has a length of 2.5cm. We also have a stainless steel front version available.

Comes with both front and rear fitting trims.

The W3 range is thermally powder coated to protect against rust. It is available in 3 colours, black, white and dark grey. The dark grey powder coating finish has a smooth matt appearance. The black and white powder coating has a slightly textured gloss finish.

If you’re looking for a larger mail chute, then the W3-2 with Trim provides this.
