MAGRACK rack actuators are designed for the building and construction segment, especially for large window applications. They are ideal for heavy-duty applications in corrosive environments. They are also extremely flexible to use as they have been designed to provide synchronized thrust at two, three or four points. Their ability to combine two motors to provide double thrust force should not be undervalued. The advance of the thrust points is always perfectly synchronized thanks to the mechanical link provided by the linking bar.
