Usage
The Cylindre double EUROPROFIL (PZ) CISA Astral S DUO 55/55 is designed for securing entrance doors in residential and commercial buildings, offering controlled access from both sides with high resistance to forced entry and advanced security features.
Advantages
- Enhanced snap resistance through a laminated steel core with six rigid and one flexible segment, reducing the risk of break-ins via cylinder snapping[1][3][7].
- High drill protection using hardened steel pins and drivers throughout the mechanism[1][3][7].
- 10-pin key bitting system increases key combinations to over 1.6 million, minimizing unauthorized duplication risks[7].
- Bump-resistant (BKP system) and special anti-picking components counteract common manipulation techniques[1][3].
- The DUO clutch system allows operation from one side even if a key is inserted on the other—practical for shared or emergency use scenarios[3][5][7].
Specifications
- Design & Materials: Brass body with nickel plating; treated steel core segments for anti-snap protection; DIN standard sintered cam; flat reversible nickel-plated brass keys[2][3].
- Durability & Standards: Tested to withstand at least 100,000 operating cycles; certified EN1303:2005 compliance and SKG** performance rating for attack resistance[3][7].
- Measurable Performance: Total length of 110 mm (55/55 mm); weight approximately between 340-345g depending on version; supports up to over 1.6 million different variances via keying systems [5][3].[7]
- Differentiating Features: Anti-drill, anti-pick, anti-bump technologies as standard; double clutch function for uninterrupted access management; supplied with three reversible keys plus code card for reproducible security copies [4][9].[5]
How it works
This mechanical euro profile double cylinder installs into compatible door locks. Each side can be operated by its own key independently thanks to the dual clutch system—ensuring door control even if a key remains inserted on the opposite side. Integrated security mechanisms resist snapping, drilling, bumping, or picking attempts.
