Zinc Alloy Keyed Casement Window Handle Lock
This keyed casement window handle is specifically designed for inward-opening windows and inward-opening/tilting windows. The base is made of zinc alloy and features a straight aluminum alloy handle with an integrated key-locking mechanism. It supports dual-angle rotation adjustment and is compatible with aluminum and PVC-U profile doors and windows. The product complies with the QB/T 5338-2018 industry standard, offering excellent anti-theft and weather resistance, making it suitable for balcony windows and casement windows in high-rise residential buildings.
Composite Metal Construction for High-Strength Locking Protection
The base is die-cast from zinc alloy, offering resistance to prying and compression while remaining resistant to deformation; the straight handle is made of aluminum alloy, providing a lightweight grip that resists bending even during prolonged twisting. The matching latch has passed a 500 N·m tensile strength test, ensuring a secure lock engagement that prevents accidental unlocking or air leakage even in high-wind conditions, effectively enhancing the anti-theft and sealing performance of doors and windows.
Surface finishes can be customized to meet customer needs, including fluorocarbon coating, anodizing, and sandblasting. A variety of color options—such as black, white, champagne, and gray—are available to complement various interior design styles, from minimalist to light luxury.
Key-operated lock cylinder design enhances security
The lock cylinder is integrated into the center of the handle. When the matching key is inserted, it locks the handle’s rotation, preventing children from accidentally opening the window and reducing the risk of falls, while also resisting forced entry. This provides reliable security for windows and doors in high-rise residences and street-facing balconies.
It supports two rotation positions, enabling both standard opening and wide-angle opening, making it perfectly suited for inward-opening and inward-opening/tilting window types. Users can freely switch between usage scenarios such as light ventilation and fully opening the window for glass cleaning.
Compatible with Multiple Profile Types; Simple Installation and Commissioning
Compatible with the vast majority of aluminum alloy and PVC-U casement window frames on the market; the base features pre-drilled universal standard mounting holes, compatible with various standard square shafts, and can be paired with gearboxes, hinge sets, and multi-point locks to form a complete set of window and door hardware. Factory batch assembly requires no additional modifications to the profiles, saving time and effort.
The internal drive mechanism operates with precision and smoothness, featuring moderate torsional damping and quiet operation, free from jamming, play, or abnormal noises.
Multiple Rigorous Tests Ensure Long-Term Outdoor Durability
1. 100,000-cycle fatigue test: After 100,000 repeated torsion cycles, the drive shaft showed no breakage or loosening, meeting the demands of long-term, high-frequency use;
2. 500-hour neutral salt spray test: Excellent corrosion and rust resistance ensures the product is unlikely to rust, lose paint, or jam when exposed to sun and rain on balconies or outdoors;
The product strictly complies with the national standard QB/T 5338-2018 for door and window hardware, meets engineering acceptance requirements, and supports bulk procurement for residential, commercial, and real estate projects.
