The rack (toothed rule) is usually placed at the bottom of a sliding gate (garage door), all along, to work with the gear of the automation mechanism. What one has to look out for when placing the rack is The distance between the gear and the rack . Specifically there must be a about 1.5 mm for the proper functioning of the mechanism, as the figure below shows.

If we do not create the right gap or, worse, if the door supports its weight on the gear, Sooner or later we will have a problem with the operation of the mechanism and possibly break his gear.

experience shows us that this is the most common mistake in the facilities of such mechanisms, many times even from “Professional installers” and the result is usually breaking the gear. For this reason, please keep the manufacturer’s relevant instructions.

• the hanger should necessary to have the same modul (diametric step) with the gear.
• to most mechanisms For domestic sliding ports or for gospels of below 2 tonnes, a gear and a diametrically diametrically used Modul 4 (M4) are used.
  
• to mechanisms for Very large door weights (over 2t), relatively common is Modul 6 (M6).
  
• must have No one in mind that the value of the modul shows the relationship between the number of teeth and the reference diameter in a gear. This means that two gears may have the same modul (and therefore cooperate equally correctly with one creamy modul) but different diameter and number of teeth.
