Friction Stays

"Friction stays, also known as window hinges or scissor hinges, are specialized support mechanisms designed for outward-opening casement and top-hung windows. Unlike traditional hinges that allow window panels to move freely with wind pressure, friction stays use an integrated sliding track and adjustable friction mechanism to hold the window sash securely at the desired opening angle. They are commonly installed on aluminum and U-PVC windows, providing controlled movement, improved ventilation, and better stability during windy conditions. The working mechanism consists of a metal arm that moves along a fixed track while a nylon or brass friction shoe applies pressure to maintain the window position without requiring additional hooks or support stays. Different types are available for various applications, including standard casement stays for side-opening residential windows, top-hung stays for upward-opening ventilators and kitchen or bathroom windows, egress stays designed for emergency escape openings with wider movement capability, and easy-clean stays that allow the sash to shift inward for safer exterior glass cleaning in high-rise buildings. Friction stays improve window functionality by providing smooth operation, secure positioning, enhanced ventilation control, and reliable long-term performance for modern window systems.
