Fire Rated Mailboxes

The Safety Letterbox Company Ltd in association with the Fire Research Laboratory worked together to create a range of 1 hour fire rated (integrity only) mailboxes. Particularly suitable when mailboxes can only be positioned within a designated fire escape route or banked in a post room which must be fire rated.

The products in this range were required to satisfy the integrity criteria given in BS476 Part 22 1987 Clause 8 for a period of 60 minutes. In addition, the mailboxes can be further enhanced by applying a finish which would conform to London Underground surface spread of flame requirement BS476 Part 6 & 7.
