Uses a knob and standard key; it can be locked and unlocked from outside with a key.
It can be opened from outside with the key even when the knob is held or blocked.
The inside knob does not lock; it only opens.
For right- or left-hand doors, adjustment can be made by changing the position of the pin-spring-screw set on the knob side.
Optional Clutch Cylinder
Removing the pin, spring and screw set on the knob side gives the product clutch-cylinder operation, allowing both opening and locking from the knob side.
It can still be opened from the front with the key even when the knob is held or blocked.
