Mul T Lock Interactive+ Threaded Mortice Cylinders

The Mul-T-Lock Interactive+ Threaded Mortice Cylinder (also known as a screw-in cylinder) offers high-security protection for commercial and residential doors. Specifically designed for metal, steel, and aluminium door applications, these cylinders thread directly into the lockcase and are commonly used with narrow-style mortice locks.

Featuring Mul-T-Lock’s advanced Interactive+ patented key platform, this cylinder utilises a unique telescopic pin-within-a-pin mechanism. This high-precision design requires both internal and external shear lines to align simultaneously for the lock to operate, providing exceptional resistance against picking, bumping, and drilling.

To prevent unauthorised key duplication, the system incorporates a patented floating element within the key itself. Keys can only be copied upon presentation of the unique security card provided with the lock.

These cylinders are available in both standard key-operated and convenient thumbturn configurations to suit your security and egress requirements. Please select your preferred option from the variants below.
