It is simple in structure, easy to install, just gently force the rack in the sliding door Automatic Window Opening System gear rack handle on the door frame, the door could be easily opened.
The opening mechanism for a rack and pinion works by converting rotational motion into linear motion. The pinion is a circular equipment, which engages a linear bar that is fitted with teeth, known as the rack; power 
is definitely put on the pinion leading to it to rotate, which subsequently makes the rack move around in regards to the pinion, which converts the rotational movement of the pinion into linear movement.
