The HR270-1 dual access horizontal mailbox is recommended for property developers who are looking for a stylish yet practical mail delivery system for cavity wall or double-glazed door panel installations. With a total capacity of just over 11.2 litres, it is ideal for larger office blocks and apartment building, and its compact dimensions of just 270 x 110 x 380mm (width, height, depth), allow it to be installed in almost any wall or glazed front. The HR270-1 letterbox is supplied with a 2mm aluminium panel.

    Made for banking, the HR270-1 front entry rear retrieval letterbox is a popular choice for developers looking to install an integrated post bank of anything up to 60 units and more. While typical bank sizes include 5 – 25 units, the only limit on design is the space you have available.

    Contact us to discuss the Post Boxes UK integrated service, which includes everything from design and initial drawings through to delivery and installation.


    As an in-front out-back mailbox, the HR270-1 horizontal postbox can be specified for both double-glazed and through-wall installations.

    It works exceptionally well in cavity wall situations and each unit is supplied with a 2mm front panel to secure the mailbox in place. Installation should be done by a fully qualified builder or carpenter.


    The HR270-1 horizontal post box is offered in standard RAL, non-standard RAL, and Class 0 fire resistant paint (aka London Underground specification) options to complement internal lobbies and exterior landscapes.


    Lead-time for the HR270-1 communal rear access mailbox is 3 to 4 weeks from order confirmation. In the case of larger mail bank installations, further lead time may be required, but we will inform you of this during the order process. For up-to-date information, please contact Post Boxes UK.

It is large enough to accept A4 documents without bending, yet it can be installed into any door entrance or wall cavity. Stylish and secure, it is a great investment for property developers and a practical addition to any lobby or reception area.
