Key Features and Advantages
Bucalu’s patented anti-falling engineering ensures secure connections between the friction stay, fixed frame, and sash, effectively reducing the risk of detachment and improving safety.
A clamping locking system combined with back locking points provides anti-prying performance, meeting the EU RC2 safety standards.
The S-Plus series classic handle ensures a more intuitive user experience and superior comfort.
The coplanar design ensures the frame and sash align seamlessly when closed, offering a clean look while making maintenance and cleaning easier.
Optional full or half restrictor provides the flexibility for small-angle micro-vent, enhancing airflow while minimizing the risk of falling.
A triple-layer sealing process with adhesive tape and an anti-shrinkage clamping design significantly enhances sealing performance, more stable and durable.
