Personalised Through-Wall Post Box | Anthracite Grey Double-Sided Letterbox

Modern Design Meets Practical Security

Upgrade your property's entrance with the Personalised Anthracite Grey Through-Wall Post Box from BK Signs. Designed for modern homes, walls and garden fences, this sleek mailbox combines a contemporary finish with a practical two-sided design for convenient everyday mail collection.

Unlike a conventional wall-mounted post box, this through-wall letterbox allows post to be inserted from the street side and retrieved from inside your property. It's an ideal solution for entrances where you want to receive mail without opening your gate or allowing access to your garden.

Personalise the exterior with precision-cut vinyl lettering featuring your house number and street name, creating a smart, distinctive finish that complements your home's exterior.

Important Installation Information

This is a through-wall letterbox rather than a conventional surface-mounted mailbox. Before purchasing, measure the thickness of your wall or fence and confirm that the adjustable depth of 190–260 mm is suitable for your installation.

The wall or fence must be prepared with an appropriately sized opening, and the installation should be suitable for the product's dimensions.
