LD-020 Window Stay Casement Window Hinge Hardware | Factory Wholesale Supplier

This window stay and casement window hinge hardware delivers smooth, controlled opening and secure positioning for UPVC, aluminum, and timber casement windows across residential, commercial, and architectural projects. The nylon friction washer system locks the sash at any angle without slipping, removing the need for extra props while enabling precise ventilation adjustment.

304 stainless steel construction provides reliable anti-corrosion performance for outdoor installations, while galvanized steel variants offer cost-effective solutions for dry inland climates. Eight standard lengths ranging from 8-inch to 24-inch suit sash heights between 600mm and 1800mm, with customizable stack heights compatible with European, American, and Asian window profile channels.

Built-in safety and convenience functions include an optional opening restrictor (limits gap to 100mm for child protection) and a dedicated 15° easy-clean position to access exterior glass from indoors. The universal reversible design fits both left-hand and right-hand windows without separate stock items, and concealed mounting channels hide screws for a neat minimalist finish. We support full OEM customization including laser branding, bespoke finishes, and matched hardware sets for window manufacturers and architectural hardware distributors.
