The Lockwood’s Modular Cylinder Extensions provide a simple and effective method of producing an extended oval cylinder.
Extended cylinders are often required where a door thickness of 50mm or greater, or when the mortice lock is mounted off centre in the door. The extra length in the cylinder is required to bring the face of the cylinder out from the door and escutcheon to enable use of the key.
Virtually any length cylinder can be made by stacking as many or as few extension pieces as required together and screwing them into the back of a special extended cylinder base.
The desired cam required for the special lock function is attached to the end of the extended cylinder and then it is ready for installation.
