Chain Actuators are normally fitted to vertical windows. Heavy Duty Chain Actuators with a higher push/pull force (200-1000N) can also be fitted to rooflights and domes. Available in various opening stroke sizes (50-1200mm) and colours (White, Black, Silver) to suit the window.
Twin Chain Actuators can also be supplied for wider windows where multiple push points are required.
