Product Description
Recessed Sliding Lock
This recessed sliding lock features a sleek, concealed, elongated design with smooth sliding and locking operation. Red and green status indicators provide clear visual feedback, while compatibility with H021 and H022 dual-wheel systems ensures versatile application across aluminum and PVC-U profile doors and windows.
Precision-Engineered Zinc Alloy Construction
Crafted from high-strength zinc alloy through one-piece die-casting, this lock delivers exceptional durability and impact resistance. The robust structure maintains integrity even under long-term, high-frequency use without loosening or breaking.
The surface features a high-performance fluorocarbon coating that has passed rigorous testing, including 500-hour neutral salt spray and 4H hardness abrasion resistance tests. This ensures UV resistance, rainproof performance, and corrosion resistance for long-term outdoor use without fading, peeling, or rusting.
Available in classic black and white finishes, with custom colors and surface treatments available upon request. The flush-mounted design integrates seamlessly with window sashes, eliminating protruding edges to prevent bumps and scratches while complementing minimalist interior styles.
Intuitive Safety Features
Red and green status indicators allow instant distinction between open and locked states, providing simple operation and resistance to accidental activation. The hook-style latch engages securely to effectively prevent doors and windows from accidentally sliding open.
