Lorient has added a new slimline fire and security rated letterplate into its door hardware protection range.

When letterplates are added to Fire doors, elements of the fire-resistant Door core are removed and replaced with ironmongery which has a higher thermal conductivity. This can create a weak point in the door, where fire can take hold and affect the integrity of the doorset. That’s why fire-rated ironmongery must be used on timber doorsets and be tested to a relevant standard – often accompanied by an intumescent kit.

Lorient solution

The new slimline RJ007 letterplate from Lorient combines fire and Security performance with functionality and aesthetics. Designed to meet the exacting security standards of TS008:2015, it is tested to withstand a series of physical tests based on the common methods of burglary. It features a pivoting stay mechanism that reduces the opening to 37 degrees for protection against key ‘fishing’ and lock manipulation.

The RJ007 can provide up to 30- and 60-minutes fire resistance (FD30 & FD60) and is tested in accordance BS 476-22:1987; and smoke tested in accordance with BS EN 1634-3:2004. It is CERTIFIRE (CF5688) approved from Warringtonfire Testing & Certification Limited; and is TS008: 2015 accredited and Document Q and PAS 24:2016 compliant.

The letterplate consists of a minimal internal flap projection of only 14mm from the door making it aesthetically less intrusive; while the unrestricted door opening allows the door to open fully without the risk of the letterplate or the interior wall being damaged. It’s available in a range of finishes to complement the fire door as required.

Doug Law, Lorient’s Technical Director told SJUK: “I’m delighted to introduce the RJ007 fire and security letterplate into our wide range of door hardware solutions. The letterplate has successfully completed rigorous security tests meeting the requirements of (DHF) TS008: 2015; as well as fire resistance testing for 30 & 60 minutes in accordance with BS 476-22:1987 – the combination of these tests is particularly onerous to achieve. You can therefore trust that the RJ007 will perform reliably and effectively, ensuring the safety and security of your property and its occupants.”
