CISA Astral S Anti-Snap Cylinders  Cisa Astral S anti-snap lock cylinders provide an effective solution to combat the serious increase in both lock snapping and key bumping attacks across the UK.  Astral S offers excellent features at a very cost effective price for those seeking extra security on a tight budget. 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 Cisa Astral S range resists this form of attack due to its Patented laminated snap-resistant steel core. The steel laminates are visible from both ends of the cylinder which creates a unique visual deterrent. The Cisa BKP bump key device is fitted as standard to all Astral S cylinders, to prevent entry by bump keys. These features result in the Astral S range achieving;   British Standard Grade 6 EN1303:2005 Certification Kite Marked for all insurers requirements
