The Aqara Adjustable Cylinder is compatible not only with the Aqara U200 smart lock but also with other brands of smart locks. A major advantage is its modular design, allowing the cylinder length to be freely configured in both directions relative to the door’s centerline, making it suitable for lock mechanisms designed to accept nearly any Euro profile cylinder. It comes with 4 extensions on each side.
Main Features:
- Adjustable Length: The special design of the Aqara adjustable cylinder allows the length to precisely match the thickness of the door using the extension elements included in the package. The outer side can be extended by up to 20 mm (with 4 extensions), and the inner side can also be extended by up to 20 mm (with 4 extensions).
- Excellent Compatibility: The device is compatible with the Aqara U200 smart lock and can naturally be used with other smart lock solutions designed for Euro profile cylinders.
- Durable and Secure Design: The cylinder is made of robust materials that resist wear over time while meeting the highest safety standards.
- Easy Installation: Thanks to the adjustable structure and the intuitive installation guide, the cylinder can be mounted quickly.
- Internal Innovations: The included reinforcement rod set ensures that the cylinder remains stable even when extended.
- For Universal Door Sizes: The cylinder fits all standard European lock types, whether for new or existing doors.
