Fire Rated All Aluminium 12 Inch Letterboxes
Fire Rated All Aluminium 12 Inch Letterboxes
Features of the fire rated all aluminium 12 inch letterboxes are:
- 1 hour fire rated - for FD30 and FD60 fire doors
- Special intumescent lining expands to 50 times its size, sealing any gaps in the door hardware
- Heat absorbing washers act as a heat sink to keep the metal screws away from the plastic and potentially melting it
- 180 degree opening flap means the flap will not snap off if opened too far - the problem with all 90 degree opening letterboxes
- Outwards facing brushes create an Anti-Vandal feature as it prevents people from placing unwanted items in to the cavity
- Outwards facing brushes also means better draught proofing and makes it easier to post letters through
- Matt finished plastic frame conceals any scratches that may be caused by screwdrivers during installation
- Blind bolts to the exterior of the letterbox prevents the outer frame being unscrewed from the door externally
- An internal water seal prevents water getting in to the door or panel, and stops letters getting wet
- Ultra-flexible springs can withstand the flap opening thousands of times without breaking
- Revolutionary self-aligning assembly feature
- Tested and conforms to many testing standards including BS EN1303:2005
