FR120MBH Fire-rated Mailboxes

Horizontal letterbox, fire-rated to 120 minutes. 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. Internal use only.

Features and benefits:

• Robust metal fabrication.
• Fire-rated mailboxes include a number of specifically developed features to meet Fire Rating standards BS 476-22:1987 Clause 8 which outlines fire testing on building structures.
• The lock included in fire-rated products uses a fire cover to limit the access for fire to the mailbox lock.
• The letterbox 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.
• This mailbox will also comply to Secured by Design requirements where applicable (contact manufacturer for more details).
• Aperture restrictor for mail theft protection.
• Two numbered keys per box. Security lock with 500 variations.
• Stainless steel hinge.
