Product Description
14-inch, 22-slot, 3.0mm-thick 304 Stainless Steel Heavy-Duty Four-Link Hinge
This extended-length, heavy-duty hinge is specifically designed for large-size casement windows. Precision-stamped from 3.0mm-thick 304 stainless steel sheet, the 14-inch extra-long arm fits standard 22mm door and window profile grooves. The four-link mechanism offers high load-bearing capacity, wide opening range, and excellent corrosion resistance, making it the core load-bearing hardware component for large-sized thermal break aluminum floor-to-ceiling windows and heavy-duty outward-opening windows.
Premium 304 Stainless Steel Construction
Stamped from 3.0mm-thick SUS304 stainless steel sheet for robust structural rigidity and exceptional load-bearing capacity. Verified through 500-hour salt spray testing for superior corrosion resistance in coastal, outdoor, and humid environments.
Four-Bar Linkage Mechanism
Extended four-bar linkage structure provides stable triangular mechanical support at wide opening angles. Ensures smooth operation, prevents sash wobbling, and withstands strong wind impacts while maintaining precise opening control.
Precision Engineering
Precision-riveted hinge points with solid rivets ensure tight fit and smooth, low-noise operation. Complies with QB/T 5338-2018 standards and passes 100,000-cycle durability testing for long-term reliability.
