A double-hook mortise lock for sliding doors. Two steel hooks swing into the frame and grip it, giving two-point locking that a standard latch can't. It works with traditional handles and Grisoll smart locks such as the TORO.
Key features
- Two-point locking: twin hooks resist the door being lifted or levered.
- Stainless steel: corrosion resistant for long-lasting performance.
- Euro profile cylinder: accepts a standard Euro cylinder.
- Two backsets: 28mm or 35mm to suit narrow sliding-door frames.
Will it fit my door?
Measure the backset of your current lock: the distance from the edge of the door to the centre of the cylinder hole. This lock suits wood, aluminium and steel sliding doors 30–120mm thick. If you're unsure, send us a photo of your lock with a tape measure.
