CISA Astral S Euro Double Cylinder

The CISA Astral S Euro Double Cylinder is a high-security, snap-resistant lock cylinder designed to protect your property against common forced entry methods. It features a unique laminated steel segment pack that runs through the core of the cylinder, providing exceptional resistance to lock snapping and pulling. Additionally, the cylinder is engineered to resist picking, drilling, and bump key attacks.

A key benefit of the Astral S is its double clutch (or emergency) system. This allows you to operate the lock from the outside even if another key has been left in the plug on the inside of the door. The cylinder is non-handed, meaning it offers equal security performance from both sides.

This cylinder is available in a wide selection of overall lengths (ranging from 60mm to 100mm) and offset sizes (A-side from 30mm to 50mm, B-side from 30mm to 60mm). It is also available in both Nickel Plated and Polished Brass finishes. Please choose your required size and finish from the options below.

Each cylinder is supplied with three reversible flat keys, a cylinder retaining screw, and a security code card for key duplication.
