The HR270-3 triple height rear retrieval dual access mailbox is most commonly specified for high density and shared office door entrance lobby installations. A high volume mailbox with a capacity exceeding 33.85 litres, it is ideal for larger apartment buildings and multiple-occupancy office blocks that receive bulk post deliveries on a daily basis. EN13724 compliant and Secured by Design Homes Guide 2016 compliant, this high capacity rear access post box can be installed within any double-glazed panel or cavity wall, where it will provide a secure mail delivery system.

    As an in-front out-back letterbox, the HR270-3 can be banked together with other units with ease. Post Boxes UK offers an integrated service for property developers and management companies, which includes planning, schematic drawings and delivery.

    While typical installations include 6 to 30 mailboxes, we do not impose any restrictions on size, and can easily install larger mail banks of 60+ units if requested.


    A versatile investment, the HR270-3 communal postbox is designed for both through-wall and front of building applications. The first option is relatively easy and can be installed into any cavity wall.


    Standard and non-standard RAL colours are available for the HR270-3 multiple-occupancy mail box. They can also be specified with Class 0 fire-resistant paint (aka London Underground specification) and fire extinguisher upon request.


    3 to 4 weeks is the standard lead-time for HR270-3 communal mailbox installations. Smaller bespoke projects may be delivered sooner, and larger applications exceeding 30 units may take slightly longer. We will provide you with an estimated completion date on receipt of your order. If you have a tight deadline, please contact us for up-to-date information.
