The transmission shaft system enables you to have a more reliable system by eliminating pulley adjustments that are necessary with traditional systems. A main steel rod is installed at the top of the opening all along the building and serves as a transmission shaft for the curtains. Once the rod is put into motion it enables the cables that are holding the curtains to roll up around it, also making the curtains go up or down automatically. The Maxum actuators are heavy duty and reliable. They are always supplied with potentiometer for more precision. There is also the possibility to replace the corner pulley with a high performance chain system to eliminate the corner tension on the main steel cable.
