The HR300-2 front entry rear retrieval letterbox offers a total capacity of 25.4 litres over dimensions of 300 x 220 x 385mm (width, height, depth). A double-height postbox suited to busy receptions and mail delivery areas, it remains a popular choice with property developers who are looking to install a stylish yet secure mail bank in a cavity wall or double-glazed panel. As you would expect from a letter box of this quality, the HR300-2 is EN13724 approved and meets the security guidelines outlined in Secured by Design’s Homes Guide 2016. A 2mm aluminium panel is supplied for through-wall installations, while a 24mm thermally broken plate is provided for double-glazed applications.

    Whether you are looking for a single unit or a post box bank of 60+ mailboxes, Post Boxes UK can help. Our integrated service includes planning, design drawings, delivery and installation, with no job too big or small.

    The HR300-2 double-height letterbox is specifically designed to be banked together with matching units, and thanks to its innovative design, it can be secured within double-glazed panels without the use of additional supports. Please contact us for more information and a personalised quote.


    The HR300-2 communal postbox comes with two standard installation options – through a standard cavity wall or within a pane of double-glazed glass.

    In the case of glass installations, we will supply a 24mm thermally-broken front panel that holds the mailbox in place without the need for additional internal supports. Once installed, the entire bank of mailboxes are self-supporting, but glazing experience is needed, and we strongly recommend that you hire the services of a qualified glazing contractor for such applications.


    Standard RAL colours and non-standard RAL colours are available for the HR300-2 rear access post box.


    Order the HR300-2 rear access communal letter box today and we will endeavour to deliver it within 4 weeks. Additional lead-time may be required for large mail bank projects of 30+ units, and smaller projects may be delivered sooner. We’ll provide you with up-to-date delivery information on receipt of your order.
