NUKI Cisa Astral S 35/40 Euro Profile Double Cylinder - Anti-Snap, Anti-Bump, Anti-Drill, Anti-Pick, 3 Reversible Dimple Keys, Nickel Plated, 75mm Total Length

High-security Euro profile double cylinder engineered for residential and commercial doors where forced entry resistance is non-negotiable. The Cisa Astral S 35/40 combines a patented dimple key profile with hardened steel pins to defeat snapping, bumping, drilling, and picking attempts, meeting the rigorous demands of BS EN 1303:2005 Grade 6 durability and Grade C corrosion resistance.

Advantages

Every component works to keep intruders out: a solid brass body with nickel plating resists corrosion for 480 hours in salt spray, while 10 hardened steel pins and a special pin configuration neutralize common attack methods. The patented bumping resistance system and anti-drill protection add layers beyond standard cylinders. Supplied with three reversible dimple keys and a security card for controlled duplication, this cylinder is built for long-term reliability—tested to 250,000 cycles and fire-rated for 30/60 minute doors under EN 1634-1.

• Front doors, apartment entrances, and commercial premises requiring high security
• Fire doors (30/60 minute rating) where certified hardware is mandatory
