Mottura locks specifically designed for aluminium doors and frames. Series 41 includes double-bit mortice locks for aluminium profiles with a horizontal faceplate, available in several configurations for both replacement work and new installations.

Mottura Series 41 locks for aluminium frames are available in side-locking and three-point versions. The range includes models with four locking turns, different locking arrangements and versions with or without latch, so they can be matched to different frame configurations.

These mortice locks are particularly useful when replacing an existing Mottura Series 41 lock, allowing the original aluminium-frame configuration to be retained when the corresponding replacement model is available.

To select the correct lock, compare the model code, dimensions, backset, presence of the latch and any connection to vertical rods. Correct identification helps avoid compatibility problems during replacement.

If you need to replace an old aluminium-frame lock and cannot identify the model, contact us with the code stamped on the lock or send photographs and measurements. We can help identify the compatible Mottura Series 41 version before purchase.
