SPECIAL CYLINDER TURNING HALF WAY (COMPATIBLE FOR LOCKWOOD ALUMINUM DOOR )

DESCRIPTION

The Unique Design of Lockwood Half-Turn CylindersLockwood’s specialized profile cylinders, often used with their mortise locks on aluminum doors, are a unique and highly specific component of a larger security system. The design is far from a standard, interchangeable part; rather, it is a deliberate engineering choice to ensure compatibility, function, and security. The defining features of these cylinders are their half-turn mechanism, a proprietary cam shape, and an unconventional installation orientation.

The Half-Turn Mechanism and Its FunctionThe most striking characteristic of these cylinders is that they are designed to turn only halfway (180 degrees). Unlike a conventional cylinder that rotates 360 degrees, this limited rotation is the intended way for the cylinder to operate the lock’s bolt.

APPLICATION

Another crucial and unusual aspect of this system is the upside-down installation of the cylinder. This is not a mistake but a fundamental requirement for the lock to function correctly. The specific orientation ensures that the proprietary cam is positioned correctly to engage with the mortise lock’s mechanism. If a locksmith were to install this cylinder in a standard, right-side-up orientation, the lock would not operate as intended. This specific installation method is a key identifier of this specialized Lockwood system and further highlights its incompatibility with other lock components.
The Half-Turn Mechanism and Its Function The most striking characteristic of these cylinders is that they are designed to turn only halfway (180 degrees). Unlike a conventional cylinder that rotates 360 degrees, this limited rotation is the intended way for the cylinder to operate the lock’s bolt. This design is directly linked to the internal workings of the specific Lockwood mortise lock it is paired with. When the key is turned, the unique cam on the cylinder rotates to engage the lock’s mechanism, retracting or extending the bolt. This half-turn movement is sufficient for the lock to function, and it is a key reason why a standard cylinder, which is meant to rotate fully, will not work in this system.
