Australian-Style Sliding Door Hook Lock
This Australian-style sliding door hook lock is a single-cylinder, key-operated lock designed specifically for sliding doors. Its hook-style latch provides strong locking force and is compatible with sliding doors and windows made of aluminum or PVC-U profiles. Strictly compliant with the QB/T5338-2018 industry standard, it is weather-resistant, durable, and offers comprehensive performance specifications, making it the mainstream lock choice for residential and commercial balcony sliding doors.
Zinc Alloy + Aluminum Alloy Composite Material for Long-Lasting Durability
The lock body’s key load-bearing components are die-cast from zinc alloy, while the housing is made of aluminum alloy. The robust overall structure resists deformation from long-term sliding and prevents the latch from breaking. Multiple surface coating options are available, with white, black, and silver as standard colors. Custom surface finishes are also supported to match the color schemes of various doors and windows.
Excellent temperature and humidity resistance; suitable for ambient temperatures ranging from -20°C to 60°C and humidity levels from 10% to 90%. It performs reliably on outdoor balconies in both humid southern regions and cold northern climates.
Single-cylinder key mechanism with high-strength latch protection
1. Single-cylinder lock core configuration: Comes standard with 2 C4-spec keys. The key cut design offers high security and superior anti-theft performance; if a key is lost, a replacement can be made without needing to replace the entire lock;
2. 500 Nm ultra-strong latch pull force: The latch pull force meets the 500 Nm standard. Once locked, the latch engages firmly with the strike plate, preventing doors and windows from being blown open in high winds and effectively preventing theft and accidental door slippage;
Having passed a 100,000-cycle fatigue test, the internal mechanism operates smoothly without jamming, ensuring no loosening or failure even with long-term, high-frequency use.
Standardized installation dimensions for simple, hassle-free assembly
The screw hole spacing is uniformly set at 82 mm, making it compatible with the standard drilling patterns of mainstream Australian-style sliding door profiles on the market. No need for new tooling, enabling high-efficiency batch assembly at door and window manufacturers. Installation steps are simple, and commissioning is straightforward.
Compatible with both aluminum and PVC-U—the two mainstream window and door profiles—it is suitable for applications such as balcony sliding doors, partition sliding doors, and commercial sliding entrance doors.
Rigorous Testing and Certification for Long-Term Outdoor Weather Resistance
1. 500-hour neutral salt spray test: Outstanding rust and corrosion resistance ensures the product remains rust-free and operates smoothly even after prolonged exposure to sun and rain;
2. Complies with the QB/T5338-2018 national standard for door and window hardware, ensuring quality compliance and hassle-free project acceptance;
The entire locking system operates reliably, requires minimal daily cleaning and maintenance, and resists fading and paint peeling over time, ensuring long-term, stable performance for the corresponding doors and windows.
