Structural Integrity
in Sliding Dynamics

The Elite Series Professional Sliding Sash Crescent Lock is the result of rigorous kinetic testing within Luoqi Hardware's safety laboratories. Designed to surpass the limitations of standard Steel Window Accessories, this professional-grade lock provides the compression force necessary to secure large-format sliding sashes, ensuring a hermetic seal within the Architectural System.

The "Elite Series" logic incorporates an anti-lift hook geometry, a critical defense against common bypass techniques used on sliding windows. Every crescent lock is precision-forged from a high-tensile zinc-aluminum composite, ensuring that the Durable Door System and window units remain unassailable under external pressure.

Operating on a "Zero-Friction" cam track, the Professional Crescent Lock provides a smooth, progressive locking sequence. This minimizes the wear on internal Strip Lock Systems and adjacent Quality Door Fittings, extending the operational life of the hardware set to over 350,000 cycles without mechanical degradation.

Surface protection is ensured by our signature 2026 PVD-Shielding. This multi-layer finish not only matches the "Elite" aesthetic but also provides a non-porous barrier against the corrosive effects of urban industrial atmospheres, securing Luoqi Window Hardware's position as the premier choice for coastal developments.
