Soft Geometry,
Hardened Performance

The "Circular Design" logic is not merely visual; it is ergonomically superior. The rounded lever body provides a natural pressure distribution during the locking cycle, reducing the effort required to actuate internal Strip Lock Systems. This makes it an ideal choice for large-format sliding sashes where repetitive operation is common.

In terms of Architectural System compatibility, the Circular Crescent Lock features a low-profile base plate, allowing for a flush-fit appearance on both narrow-frame aluminum and composite profiles. The internal Secure Access Control cavity is micro-machined to house encrypted NFC status sensors without disrupting the lock's external fluidity.

Each unit is finished with a "Velvet-Touch" PVD process, providing a satin-smooth surface that is exceptionally resistant to micro-scratches and oxidation. This ensures that the Quality Door Fittings aesthetic remains pristine, reflecting the Luoqi Window Hardware commitment to long-term luxury.
