Product Specification

Double-Sided Key Sliding Window Lock

This double-sided key sliding window lock features a dual-sided operation design, paired with a fork-type transmission mechanism and red and green status indicators. It allows for locking and unlocking from both the interior and exterior, offering intuitive and convenient operation. It can be combined with sliding hinges to form a five-piece door and window set and is compatible with aluminum alloy and PVC-U profile doors and windows. It offers excellent security and anti-theft performance and is widely applicable to single-panel and double-panel sliding doors, as well as various types of folding doors and windows.

High-Quality Materials, Precision Craftsmanship

The lock body is made of high-strength zinc alloy through one-piece die-casting, resulting in a compact and robust structure that resists deformation and wear. It can withstand long-term, frequent locking and unlocking operations, ensuring a long and stable service life. The fluorocarbon coating on the surface offers outstanding weather resistance. It has passed a 500-hour neutral salt spray test and a 4H surface hardness test, effectively withstanding erosion from complex outdoor environments such as sunlight, rain, and temperature fluctuations. It remains resistant to rust, fading, and paint scratches or peeling even with long-term use. Available in two classic standard colors—black and white—while also supporting custom colors and surface finishes based on customer requirements. The elongated, recessed design integrates seamlessly with door and window assemblies, creating a clean and attractive appearance while providing resistance to bumps and impacts.

Fork-Type Transmission + Red/Green Indicators: Dual Upgrades for Safety and Convenience

The innovative fork-type drive design ensures smooth and stable operation, with the latch engaging evenly to prevent loosening or disengagement when locked. Paired with red and green status indicators, the open and closed states of the door or window are immediately apparent, allowing for quick identification of the lock’s status. Operation is simple, reducing the risk of accidental misuse. The dual-sided lock cylinder design allows for locking and unlocking from both the inside and outside, providing strong anti-theft and anti-pry capabilities while preventing children from opening windows without permission, significantly enhancing the security level of doors and windows.

Easy Installation, Wide Compatibility

The lock body features standard mounting holes, saving time and effort during on-site assembly and effectively reducing assembly labor hours and labor costs for door and window manufacturers. Compatible with the two mainstream door and window profiles—aluminum alloy and PVC-U—it can be paired with sliding hinges to form a five-piece door and window set. It supports various door and window types, including single-panel and double-panel sliding doors, folding windows, and folding doors, making it suitable for residential, commercial, and construction projects.
