H370 1 Stainless Steel Mailbox Post Box Letter Box

H370 1 Stainless Steel Mailbox Post Box Letter Box

Another commonly specified letter box, the model H370-1 stainless steel mailbox is a wider yet shallower version of our best selling model H300-1 unit. This multi occupancy post box is best suited to larger lobby areas in which a focal point is to be achieved - its width lending itself well to a landscape style. It is suitable for both small scale apartment and flat projects and the largest of multi-use developments. It is also available as an extra large capacity mailbox - our models H370-2 and H370-3.




This horizontal stainless steel mailbox has dimensions of 370mm width, 110mm height and a standard depth of 270mm. A popular unit it has become an industry standard across Europe for high density residential schemes, commercial office developments and student accommodation projects. It is a front-entry front-retrieval unit (in-front, out-front) and conforms to EN13724 (accepts A4 mail without having to fold or bend the post, has anti-theft baffle to aperture) and is Royal Mail approved. Where applicable, it complies to Secured By Design requirements (clauses 21.19 and 24.6).

The model H370-1 is designed to incorporated and assembled into larger banks of post boxes - typically, from small banks of 6 units up to larger banks of 300+ units. The model H370-1 mailbox is most suited to large scale city centre residential schemes.

The H370-1 is available in marine grade 316 satin (brushed) stainless steel.

It is suitable for both internal and external use with a choice of different casings, surrounds and support legs.

The model H370-1 can also be fitted with an internal fire extinguisher. This is a much more economical solution than specifying a bank of fire rated letter boxes.
