CISA Astral S Anti-Snap Cylinders  Cisa Astral S anti-snap lock cylinders provide a reliable and effective solution to combat the serious increase in both lock snapping and key bumping attacks across the UK.  Astral S offers excellent security features in a well proven high quality Italian made cylinder from Cisa - one of the largest high quality lock manufacturers in the world. Lock snapping is by far the quickest & easiest method of entry by the modern burgular. Snapping involves the breaking in half of the lock cylinder and its removal from the door by common hand tools, usually in under 30 seconds.

The steel laminates are visible from both ends of the cylinder which creates a unique visual deterrent. The laminates flex if snapping is attempted. The Cisa BKP bump key device is fitted as standard to all Astral S cylinders, to prevent entry by bump keys.
