Product Specification

Sliding Window with Key-Operated Single-Bar Lock
This sliding window lock features a minimalist, elongated, recessed design. It is equipped with a key-operated locking mechanism and red and green status indicators. Installation and operation are simple and intuitive. It can be paired with a sliding hinge to form a five-piece door and window hardware set and is compatible with aluminum and PVC-U profile doors and windows. Offering outstanding security and protection, it is widely used in single-leaf and double-leaf 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 robust and compact structure that resists deformation and wear, ensuring long-term reliability even with frequent opening, closing, and locking of doors and windows. The surface is treated with a fluorocarbon coating that offers excellent weather resistance. It has passed a 500-hour neutral salt spray test and a 4H surface hardness test, effectively withstanding the erosion of complex outdoor environments such as sunlight, rain, and temperature fluctuations. It remains resistant to rust, fading, and paint scratches or peeling even after long-term use. Available in two classic colors—black and white—as standard, the product also supports personalized customization of colors and surface finishes based on customer needs. Its long, recessed design lies flush with the door or window, preventing protrusions or collisions, and offers a sleek, elegant appearance.

Red and Green Status Indicators: Intuitive and Secure Locking
Equipped with red and green status indicators, the locked and unlocked states of doors and windows are immediately apparent, allowing for quick identification of their operational status and ensuring convenient, worry-free operation. Combined with a key-operated lock cylinder, the system effectively prevents theft and forced entry once locked, while also preventing children from opening doors and windows without permission, significantly enhancing home security. The latch engages tightly and securely, preventing disengagement or loosening during sliding operations.

Easy Installation and Wide Compatibility
Standardized pre-drilled mounting holes save time and effort during on-site assembly, effectively reducing assembly time and labor costs for door and window manufacturers. The product is compatible with the two major window and door profiles—aluminum alloy and PVC-U—and can be paired with sliding hinges to form a five-piece hardware set. It is suitable for various window and door types, including single-leaf, double-leaf, and sliding doors, as well as folding windows and folding doors, making it ideal for a wide range of applications, including residential, commercial, and construction projects.

The locking performance is stable and reliable, backed by an official 5-year warranty. Offering durability, peace of mind, and outstanding value for money, these locks are the preferred choice for door & window manufacturers, hardware wholesalers, and project procurement teams.
