Description

The External Wall-Mounted Post Boxes for Flats – Sparrow is a compact, space-saving letterbox system designed for apartment buildings, multi-tenant properties, and communal entrances where depth and wall space are limited.

Crafted from galvanised steel and finished in anthracite grey powder coating, each individual box measures just 145 mm in width, making this one of the slimmest external post box units available. Whether you’re installing along a narrow corridor or into a tight entry space, the Sparrow offers a sleek and professional solution without compromising on functionality.

This model is suitable for both indoor and outdoor use thanks to its weather-resistant materials and robust construction. Each compartment is fitted with a secure cylinder lock and comes with two keys, ensuring privacy and peace of mind for tenants. A clear name card holder is included on each door for easy identification.

The bottom section of each unit is subtly angled to facilitate the accommodation of A4 correspondence and to reduce overall depth—ideal when projecting into public or shared areas must be minimised.

Please note: This model is sold as individual banks of 5 or 6. We currently do not offer bespoke installations or larger sets. Customised solutions may be available on a pre-order basis—please contact us for further details.
