A superior quality, British made Horizontal Mortice Latch and an excellent choice for both high quality residential and heavy use commercial applications. This latch has traditional case dimensions similar to many older patterns so it can normally be used as a direct replacement with little or no additional joinery work or making good required. Reversible on site to suit left or right hand hung doors and can be fitted to fire rated timber door sets in accordance with current regulations.
The long backset measurement allows fixing of door knobs away from the door edge which is a traditional feature on the mid rail of panelled doors. In addition, the medium sprung, two-way action allows knobs to be operated with ease and in both directions. If possible use knobs or handles with horizontal bolt through fixings to avoid fixing screws fouling the latch case.
For best results and long life, this latch should be lubricated with a light machine oil at least once a year.
This product has been successfully type tested for conformity to all of the requirements of BS EN 12209 : 2003 including the additional requirements for fire/smoke door use - certificates are available on request.
Fire rating is only applicable to this product when fitted to timber based door assemblies of proven fire resistance as defined in BS EN1634-1 or BS476 Part 22:1987 and when fitted with appropriate intumescent material.
One latch complete with faceplate, frame keeper plate and all fixing screws.
