The Astral Tekno Pro is the advanced version of the successful Astral series by Cisa, offering protection against the most modern burglary methods. It is a cylinder that combines high certified security with durability, ideal for armored and wooden doors that require maximum protection.

The main feature of the Pro version is controlled breakage (Anti-Snap), which prevents the cylinder from being broken by external tampering.

• Anti-Snap Technology: Features a predetermined breaking point (sacrificial cut). In the event of a break-in attempt, the cylinder breaks at a specific point, leaving the rest of the body intact inside the lock, preventing entry.

• BKP (Bump Key Power) Protection: High resistance to the "bumping" burglary method thanks to a special patented system of springs and pins.

• Anti-Drill Protection: Internal pins and guides made of hardened steel protect the mechanism from drilling.

• Double-Sided Key: Comes with security keys with an ergonomic plastic handle, which can only be duplicated upon presentation of the personal ownership card (Security Card).

• Certified Security: Complies with the European standard EN 1303:2015, achieving top ratings in durability and security.

Correct Measurement: Make sure that the 30/50 dimension fits your door. The 30mm side is usually placed towards the exterior side (if there is a defender) or depending on the position of the lock on the thickness of the door. The cylinder should not protrude more than 2-3mm from the lock plate or the defender for maximum security.
