ABUS Knob Half Cylinder – The cylinder lock for the right side
The knob half cylinder from ABUS is made of high-quality material. This makes this cylinder lock particularly safe and durable. The round knob with nickel pearl surface sits comfortably in the hand and is comfortable to use. In no time at all, a door can be opened and locked again without a key.
Knob half-cylinders are used when a passage is to be used primarily in one direction or the possibility of opening and closing is only desired on one side.
This can be useful when the second side door of the garage leads directly into the garden and you use the passage to bring equipment or material outside. The knob half cylinder can also be used as a solution on external doors of rear exits, which should only be used to leave a building. Another example of application for this product is armoured latch from ABUS, in which the knob half cylinder can be mounted. It is also possible to use on doors of toilet room cells, as in this case the door should only be opened and closed from the inside.
The door closed with a half-cylinder offers as little attack surface as possible on side doors. The knob half-cylinder is designed so that the comfortably rotating and round knob protrudes on the front; on the other hand, the cylinder housing is flat and thus allows hardly any chance of manipulation by unauthorised people.
