Usage
The CISA Astral S DUO 45/45 double euro profile cylinder is designed for securing residential, commercial, and office doors where medium to high security is required. Suitable for both new installations and replacements in mechanical lock systems.
Advantages
- High resistance to snapping due to the patented steel laminated core extending throughout the cylinder length[1][6].
- Advanced protection against picking, drilling, and bumping methods with a ten-pin key bitting system[1][4].
- Reversible operation allows key use from either side, even when a key is inserted in the opposite end (double clutch system)[4][6].
- Able to be included in masterkey or keyed-alike systems for convenient access management[2][6].
- Slightly heavier than standard cylinders at approximately 320g due to robust construction—a minor consideration during installation[4].
Specifications
- Design: Euro profile double cylinder (45 mm external / 45 mm internal); brass body and plugs; nickel-plated finish; self-lubricating DIN-standard steel cam; overall length: 90 mm[3][4][6].
- Durability & Certification: Tested up to 100,000 cycles; complies with EN1303:2005 standards (Attack Resistance: grade 1 / Key Related Security: grade 6 / Durability: grade 6); ICIM certified[1][2].[6]
- Performance: Ten-pin system—six active and four passive pins—with over one million possible key combinations; resistant against snapping (+40%), picking, bumping (BKP device), drilling (hardened steel pins), and impression attacks.[1][4]
- Differentiating Features: Patented snap-resistant dual-material core visible at both ends for visual deterrence. Standard supply includes three reversible keys and code card for secure duplication control.[1][3]
How it works
The cylinder installs into compatible euro-profile locks, enabling secure locking from both sides of the door. Its ten-pin mechanism ensures reliable performance against common break-in techniques while allowing smooth operation—even if a key remains inserted on one side.
