## Long description

The NUKI Cisa Astral S 40/45 is a mechanical euro-profile cylinder designed for door locking systems, offering adjustable security levels and compatibility with standard euro-profile locks. Built to fit residential and light-commercial doors, this cylinder provides reliable locking functionality with a conventional key operation. The product name reflects the Cisa Astral S series and the 40/45 length configuration, suitable for doors requiring an asymmetric cylinder dimension.
Advantages
The cylinder delivers precise key operation and smooth rotation, helping to reduce wear on the locking mechanism. Its asymmetric 40/45 length enables fitting into doors where different inside and outside thicknesses are present, allowing secure mounting without protrusion. The mechanical design requires no batteries or electronics, ensuring operation in all conditions and minimal maintenance needs.
Suitable for
Residential apartment and house entrance doors
Interior doors with euro-profile locking mechanisms
Renovation projects where asymmetric cylinder length is required
Light-commercial premises with standard euro-profile locks
Key specifications
Profile type: Euro-profile cylinder
Length configuration: Asymmetric 40 mm on one side / 45 mm on the other side
Operation: Mechanical key-operated cylinder
Application: Suitable for standard euro-profile door locks
Construction: Solid cylinder body for conventional locking systems
How to use
Measure the door thickness and the required internal/external dimensions to confirm the 40/45 asymmetric cylinder fits correctly. Remove the existing cylinder by opening the door, loosening the fixing screw on the edge of the door, and withdrawing the old cylinder while turning the key slightly if needed. Insert the Cisa Astral S 40/45 into the lock case, align the cam, secure it with the fixing screw and test key insertion and rotation from both sides to ensure smooth operation.
Usage recommendations
For secure and long-lasting performance, ensure the cylinder is installed by a competent locksmith or following precise installation instructions; periodically check the fixing screw and lubricate the mechanism with a lock-appropriate lubricant to maintain smooth key action.
