Double chain actuators are used to operate wide vents and windows that require multiple push points to open. Suitable for domestic and commercial applications, they can be used for the purposes of smoke and natural ventilation.
Twin chain actuators are normally fitted to vertical windows, although heavy duty double chain actuators with a higher push/pull force (200-1000N) can also be fitted to rooflights and domes.
They are available in various opening stroke sizes (50-1000mm) and colours (White, Black, Silver & Grey) to suit the window.
We also supply single chain actuators, which are suitable for windows and vents that do not require multiple push points.
