A single match or firework dropped into a postbox can quickly become a serious fire, especially in apartment building where postboxes are arranged together and the flames easily spread. Not only does this cause a hazard for occupants, it also usually results in expensive repair and replacement work.

The Cityline FR1 Postbox is designed to contain flames and heat without losing its integrity for up to 60 minutes. This allows time for the fire to be extinguished and eliminates the risk of fire spreading from one postbox to another. Special intumescent seals around the letter flap expand when heat is detected, keeping flames and heat contained. The lock is shielded, while the body of the postbox is built from heat-resisting steel.

Tested by the experts at Exova Warrington, the FR1 meets the BS476 standard. It is designed to maintain its integrity for up to 60 minutes in the event of a fire.

Suitable for recessed or surface wall-mounting. It is recommended that you use an intumescent sealant between the product and the wall in order to provide maximum fire resistance.

The FR1 is available in a wide range of colours, as shown in the colour chart above. The most popular colours are listed in the drop-down menu and can be ordered directly through our website. To order other colours, please contact us.

These items are built to order and delivery may take up to 4 weeks in certain circumstances.
