Key factors in cylinder length

1. Door thickness
2. Mortise lock position in door leaf
3. Faceplate thickness door handle
4. Faceplace thickness of inside door handle

Cylinder length calculation formula

Tltal length=door thickness + faceplate thickness of outside door and inside door handle

Outside length=faceplate thickness of outside door handle + dinension of mortise lock outside center position

Iutside length=faceplate thickness of outside door handle + dinension of mortise lock inside center position
