New Door Locking System - Ross & Bonnyman have developed an unobtrusive retractable slam locking system for shutter doors using a single handed slam action.
The new design aims to resolve the problems associated with top clearance on traditional hook locks and the obtrusiveness of the slam locks by retracting after the system is unlocked.
As the user operates the system, the lock unlocks from the door and the mechanism automatically retracts out of the way into the main body of the lock mechanism.
