The Securistyle Defender Side Hung Friction Hinge With Built-In Restrictor is designed to suit the majority of UPVC, timber and aluminium casement windows.

Its built-in restrictor mechanism limits the window opening which helps to reduce the risk of falls, making this an ideal hinge for both commercial & residential buildings.

Quick-release mechanism overcomes the restrictor and allows the window to be fully opened for easy cleaning and ventilation.
