Fire Rated 1 Mailbox with Two Hour Integrity

made in britain

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: 2012 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.
