Designed and fabricated in-house, our Telescopic Letterbox Insert offers a flexible and professional mail solution for modern homes. Built to be installed directly into brick or rendered walls during construction, these inserts provide a clean, flush finish when paired with a custom faceplate. With an extendable depth that suits walls between 240mm and 470mm, this product offers a truly versatile fit for new builds or custom masonry letterbox projects.

Ideal for matching with a custom-designed faceplate, the insert becomes the secure housing behind the face, offering a seamless and secure letterbox solution tailored to your wall depth and exterior finish.
