Forming part of our UK Modular range, this high quality British made Mortice Lock has a 3 Lever mechanism for medium security internal doors or external doors where a high security lock is not required. Incorporating a heavy duty solid brass latchbolt for superior performance this lock is an excellent choice for both high quality residential and heavy use commercial applications and is offered with the option of "Standard Sprung" or "Heavy Sprung" handle follower. Can be fitted to fire rated timber door sets in accordance with current regulations. Manufactured in Britain by Guardian Lock & Engineering.
Select "Standard Sprung" for lever handles with integral springing in the rose or backplate or "Heavy Sprung" for handles described as being un-sprung. To avoid fixing screws fouling the latch body use handles with diagonally opposed bolt-through fixings or with backplates where fixings 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.
