Our 12" Fire Check Letterplates come with an intumescent lining that expands against the heat radiated from a fire; this fills any holes preventing the risk of fire spreading for 60 minutes. Non-heat absorbing washers are also used to hold the attaching metal fixings to stop heat transfer from the metal plate to the surrounding door.
The letterplate is also Anti-Vandal™ making it the perfect choice for anyone concerned with home security.
This letterplate will replace most 300mm (12") letterplates and is suitable for wooden and composite doors with a thickness of 40-80mm.
Awarded 'Secured by Design' approval from the Association of Chief Police Officers, the letterplate also conforms to BS/EN 13724:2002 standards and is 60 Minute Fire Rated for FD 30 and FD 60 Fire Doors.
