Cylinder Locks: Half Euro compatible with the CISA Astral keyway

Half Euro cylinders, also known as single-sided Euro cylinders, provide secure, key-controlled access from one side only, making them the ideal choice for garage doors, cabinets, patio doors, and panic exit hardware. Our comprehensive range features versatile entry-level 5-pin and 6-pin mechanisms alongside high-security options, including the snap-resistant Avocet ABS Ultimate/Quantum 3-Star BS TS007 Half Euro for maximum protection. Designed for easy installation and flexibility, these cylinders are available in a variety of durable finishes such as satin chrome, polished brass, and nickel plating, with specialist options including adjustable cams, rear-fixing threads for outside access devices, and convenient keyed-alike configurations.
