Designed to open and close home windows in difficult to reach areas, electric window openers, or actuators, are exceptionally handy.
They work via a motorised folding arm that’s attached to a home window. The arm starts in a folded placement, however as it is powered by the engine, it begins to unfold. 
The arm is positioned in a way that as it starts to unfold, the home window begins to open up. To close a windowpane, the arm starts to fold back up into its original position, bringing the screen to a close.
It is simple in framework, easy to install, just gently press the rack in the sliding door manage on the entranceway frame, the door can be easily opened.
The opening mechanism for a rack and pinion functions by converting rotational movement into linear movement. The pinion is certainly a circular equipment, which engages a linear bar that has been fitted with teeth, known as the rack; power can be put on the pinion leading to it to rotate, which subsequently makes the rack move in relation to the pinion, which converts the rotational motion of the pinion into linear movement. For electric screen openers, the rack is definitely housed in exterior casing and is attached to the windows. As the pinion moves, the rack can be pushed out, starting the windowpane along with it.
These are Gear Rack For Window Opener usually suited to side hung home windows or doors, as they offer a 90-degree opening. Also, they are known as folding arm actuators and may be designed to open inwards, outwards or both methods.
The object of today’s invention is achieved, through the center equipment shaft fixed on a frame, which is fixed to the frame, is fixed to the sliding gear engages with the rack on the rail of the frame, fixed to the corresponding door there might be engaged with the stationary gear rack, the slide rack when the pushing handle on the entranceway, so that the rotation from the gear rack fixed on the entranceway, the door movement, so that the entranceway is opened, with a equipment fixed to the frame reset spring.
The object of today’s invention is to supply a device with a special dual rack door when the sliding door.
