Introducing the fire rated FR1 mailbox suitable for vertically storing A4 mail for front entry and retrieval. The FR1 mailbox has been developed to restrict the spread of fire for up to two hours only and if recessed into a fire rated wall, will maintain the integrity of the fire rated wall for up to two hours.
Fire rated mailboxes includes a number of specially designed features to meet fire rating standards BS EN 1363-1: 2019 which outline fire testing on building structures. The lock included in fire rated products uses a fire cover which limits the access to the mailbox lock.
The mailbox flap uses an inward sprung hinge to stop the flap from falling out of the box and the mailbox aperture uses an intumescent seal which expands when exposed to a large increase in temperature; closing the gap and restricting the flow of oxygen into the mailbox.

Do I really need a Fire Rated solution?
Two fire rated ranges are available to use, the first option is to meet the BS EN 1363-1: 2019 which features products with specific features and benefits that result in a ‘two hour integrity’ rating.
The second option is to meet the BS 476 Part 6 & 7 which will satisfy the demands of fire protection in most cases, and provide an affordable alternative if non-flammable materials are acceptable.
All products achieving these standards are polyester powder coated to London underground engineering standard 2-01001-002 for surface spread of flame.
How long are the Fire Rated mailboxes tested for?
Mailboxes featured in the fire rated BS EN 1363-1: 2019 range have been tested for up to ‘two hours integrity’ only. This standard typically tests the material that the product is made of to see if it will ‘fuel a fire’.
Are there any other Fire Rated options available?
All mailboxes can be fitted with a FireTrace™ which is a single use automatic fire extinguisher.
Can the dimension of the box / mail aperture be adapted?
No. The fire rated range has been tested at the specified dimensions and any adjustment in sizing will result in the mailbox not meeting the fire rating standards.
Do they meet Secured by Design?
Mailboxes can be fitted with an additional security bridge feature that will comply with the Secured by Design New Homes Guide 2024 guidelines. Combining an additional security bridge with a mailbox from the fire rated range will comply with both fire rating and Secured by Design Homes 2024 guidelines.
