One of our best selling locks and the first choice of many of our trades customers for external doors requiring a High Security 5 Lever Mortice Sashlock. The lock features a solid, hardened steel, anti-saw deadbolt with a positive 20mm throw, hardened steel anti-drill side plates and 5 pick resistant levers. Certified to BS3621 and recommended by insurance companies and the police. An ideal choice for lever handle furniture on rose or backplate and easilly reversed on site for left hand or right hand hung doors. Suitable for residential use and medium duty commercial applications and approved for use on fire rated timber door sets in accordance with current regulations.
This lock has a medium sprung latch follower and should only be used with lever handle furniture with integral springing in the rose or backplate. To avoid fixing screws fouling the latch body use handles with horizontally opposed bolt through fixings or with backplates where fixing positions are adequately spaced. NOT recommended for use with door knobs.
Can be fitted to double doors with rebated meeting stiles when used with the rebate conversion set in the Related Items section below.
Detailed advice on the selection of mortice locks and latches can be found in our [Mortice Locks & Latches Specification Guide].
For best results and long life, this latch should be lubricated with a light machine oil at least once a year.
