Use this letterbox installation channel as a guide for installing your letterbox into a brick, render or gabion wall.
Made from galvanised steel and telescopes from 240mm-470mm deep to match our Telescopic letterboxes if needed.
It will come as two pieces, one smaller that slides into the other. Simply rivet the two pieces together at your desired length. The internal space is made big enough that our letterboxes will slide in comfortably.
Suitable for use with...
- Superior (340w x 140h x 240d)
- Telescopic Landscape (340w x 140h x 240-470d)
- Telescopic Portrait (240w x 140h x 240-470d)
An installation channel is highly recommended for gabion wall letterbox installations. The channel will protect the letterbox from damage, and keep the rocks from directly weighing down on it.
