The Securistyle Defender Restricted Side-Hung Friction Hinge is a premium window hinge designed to enhance safety and functionality in residential settings. Available in 12" and 16" lengths with 13 mm and 17 mm stack heights, and in both left- and right-handed versions, it’s suitable for a wide range of side-hung PVC-u window installations. It features a built-in restrictor that limits the opening of the window to help prevent accidental falls, making it ideal for homes, apartments, and multi-occupancy buildings. A simple quick-release lever allows the hinge to be disengaged when needed, enabling the sash to open fully for cleaning or maximum ventilation, and the restrictor automatically re-engages when the window is closed.
Engineered for long-term performance, the Yale Defender Restricted friction hinge offers several design innovations that ensure reliability and ease of use. Its robust cam friction device prevents friction screw misuse, while the asymmetric location system guarantees consistent alignment and closure. The hinge’s extended enclosed end cap and vent arm design improve weather sealing and draught proofing, meeting BS 6375-1 standards, while the slot-hole-slot fixing pattern allows secure installation into PVC-u reinforcement with easy adjustment. Tested to 30,000 cycles, corrosion tested to 96 hours, and both Secured by Design approved and BBA certified, it provides peace of mind that it will perform safely and smoothly for years to come.
Did you know? Roughly 4,000 children are injured each year from falls out of windows. Installing a restricted friction hinge helps prevent these accidents while still allowing safe ventilation and easy cleaning access.
