CISA Astral S24 QD Euro Double Cylinder

The CISA Astral S24 QD Euro Double Cylinder is a high-performance security solution designed for both residential and commercial doors. Offering dual-sided key access, this double cylinder is ideal for main entrance doors requiring secure key control from both the inside and outside.

Engineered with CISA's advanced security technology, the Astral S24 features a 10-pin key bitting system alongside robust anti-drill, anti-pick, and anti-bump protection. To defend against common forced entry methods, it incorporates a unique break line and a laminated segment pack, providing exceptional resistance to lock snapping and pulling even without the support of an armoured handle. The QD (Quick Defence) system further enhances security by helping to prevent unauthorised key duplication.
