ERA, the supplier of specialist door and window hardware products, has become the first UK manufacturer to achieve a Kitemark for a range of multi-point locks (MPL). Its new MPL range meets the requirments of PAS 3612:2011, the standard that was introduced in the UK in October 2011, that covers locks installed into domestic doors of PVCu, composite or wooden construction.
Tested to 200,000 cycles, the new locks are estimated to be approximately twice the strength of existing MPLs but will fit into the same preparation routing. Security features include anti-drill plates on both sides of the gearbox and the locks hooks are hardened to prevent drilling attack. The centre gearbox, which is the same size as ERA’s existing MPL, is available in 35 and 45mm backsets and in either a Euro Cylinder or Vectis Plus version.
Group Technical Director Ben Penson describes the development of the new MPL as a move designed to anticipate the direction the market will take. He says: “There have been two new standards introduced over the past year and we have been the first manufacturer to introduce products certified to those standards on both occasions. We started development about three years ago, after Secured by Design instigated a project to have a security standard for MPLs roughly equivalent to the BS 3621 standard for mortice locks. Although there is currently no requirement for the use of a Kitemark MPL, our policy is to look to the future and develop products that will meet increasingly stringent security requirements. We believe that a Kitemark MPL will soon be a requirement for achieving a Secured by Design specification for door assemblies and we wanted to be first to market with a solution.”
Other features of the new MPL include a latch bolt that can be reversed for handing, split and solid spindle operation, a Snib shaped to the Kitemark symbol; and anti-drill plates on the top and bottom hooks. Designed to link to the MPL drive bars in the same way as the existing MPL, the shoot bolts are of a more complex design to meet the strength requirements of the standard and the new range of strengthened keeps suit both PVC and composite doors.
To meet the Kitemark requirements, the lock should be tested and supplied with the appropriate cylinder and handle furniture. Ben Penson explains: “For a Euro Cylinder lock, a 3-star rated cylinder and handle combination are required to ensure conformance. There is, however, more flexibility with hardware choice with the Vectis Plus Kitemark lock which has no cylinder and so avoids the need for the 3-star cylinder/handle combination.”
