For this indicator, all devices are divided into seven classes where the 1st class product is designed to have a door weight of not more than 20 kg and the 7th Class is a weight of 160 kg. The interval between the design weight of each class is 20 kg. The choice would be optimistic if the clerk class corresponds most accurately to the mass of the doorframe.
Nor should it be forgotten about the correct choice of the temperature regime. Hydraulic and hydromechanical requisitioners are used only to install interior doors. A special freezer should be purchased for outside doors.
