Advantages

This double cylinder lock stands out due to its robust construction and high-quality materials, which provide long-lasting resistance against wear and tear.

Additionally, it is not compatible with doors that require a different cylinder length or a thumb-turn mechanism on one side.

Key specifications

• Type: Double cylinder
• Size: 40/45mm
• Finish: Matte nickel
• Included: 3 keys
• Application: Standard door locking mechanisms

To install the ABUS 57222, remove the existing cylinder by unscrewing the fixing screw located on the side of the door edge. Insert the new cylinder into the lock case, ensuring it is centered, and secure it firmly with the fixing screw. Test the operation with the provided keys from both sides of the door before closing it to ensure the mechanism functions correctly.

What to consider before purchase

• Verify the required cylinder length (40/45mm) for your specific door thickness
• Ensure the door lock mechanism is compatible with standard profile cylinders
• Check if you require additional key copies for other family members or staff

For optimal performance and longevity, avoid using heavy lubricants inside the cylinder. If the key operation becomes stiff over time, use a specialized graphite-based lubricant sparingly to maintain smooth movement.
