Yes, it is designed for a 44 mm backset. This backset dimension refers to the distance from the door edge to the centre of the lock case. If your door is already prepared for a 44 mm setup, this sashlock is a direct match and should align correctly with your existing drilling and handle or lever furniture position.
Case size 67 mm is the lock case length, which helps confirm that the lock will sit properly within the door pocket. Combined with the 44 mm backset, these measurements are the key checks to make sure the lock will fit the door and strike arrangement without having to alter the mortice pocket more than necessary.
This Fortress sashlock is a lever operated lock (CB). Lever locks are commonly used in door security for reliable everyday locking, and this model also includes a deadbolt function as standard, helping to improve security when the door is fully secured.
It comes in a satin steel finish. If your door furniture and escutcheons are also satin steel or similar brushed finishes, this sashlock is designed to blend in neatly for a consistent look across the door.
