08 - 5 Lever & Detainer High Security Mortice Locks for Lever Handles & Door Knobs

Mortice Sashlocks are housed in the door edge and have a deadbolt operated by key from both sides and a latchbolt normally operated by lever handles or door knob furniture. Our 5 Lever and Detainer sashlocks are suitable for high security applications and are recommended as a minimum level of security on external doors by the insurance industry and police. We offer a full range of high security mortice locks suitable for the vast majority of applications from residential use through to heavier commercial situations and in case sizes from 2.5" (63mm) through to 6" (152mm). Rebate Conversion Sets for double doors are also available as an optional extra for most of our mortice locks and these can be found on the individual product pages where applicable.

When choosing locks and latches for timber doors we recommend you refer to the information in our [Mortice Locks & Latches Specification Guide] before making your selection.
