MK1 Shootbolt Locking System — 20mm Retractable Lock

The WF2937Y MK1 Shootbolt Locking System is engineered to the most exacting standards, delivering a secure, smooth-closing multipoint locking solution for French windows and casement applications. Steel shootbolts engage into robust, profile-specific solid zinc keeps to protect the vulnerable corner of the window, while mushroom cams provide additional strength and precise weatherseal compression adjustment.

Exceptionally versatile, the MK1 is suitable for low handle height applications and a wide range of French window designs — including slave window configurations via its cam-free gearbox.
