- Made from 316 grade stainless steel
- 1 hour fire rated - for FD30 and FD60 fire doors

- Heat absorbing washers act as a heat sink to keep the metal screws away from the plastic and potentially melting it
- Comes with a lifetime coating guarantee anywhere in the country
- 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
