DOORMASTER 12 Inch Letterboxes
Features of the DOORMASTER 12 inch letterboxes are:
- Has a central sleeve, meaning that it can fit in waste (mid) rails
- 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-alligning assembly feature
- Tested and conforms to many testing standards including BS EN13724
