The advantage of restraint jacks over normal models is that they are slow and softer, which keeps the door steady when open. Pump jacks will multiply the applied force and make it easier to open the door. Also, when closing the door, they prevent it from dropping suddenly and close it slowly. In the manufacture of this product, a combination of metal and plastic has been used. The metal part is made of stainless steel and has a high resistance to rust and corrosion, and the plastic part of the jack is made of compressed and unbreakable plastic with quality that can be compatible with a variety of cabinets. Pump jack is produced in two types, simple and relaxing. A pump jack is used to hold the cabinet door steady when the door is opened. The main difference between this jack and a regular pump jack is that a normal jack closes with a knock when the door is closed, and often a pump gas hinge is needed to reduce damage to the cabinet; But the mechanism of the quiet pump pump jack is such that at the end there is a shock absorber that closes slowly when the door is closed, so there is no need for a pump gas hinge. For light cabinet doors, you should not use the cabinet jack with high Newton bearing, because when closing the door, pressure is applied to the door hinge, and when opening the door, it causes it to fall. Usually, for doors up to 70 cm, an 80 Newton jack is used, and for doors up to 70 cm, up to 1 meter, a 100 Newton jack is used, and for over 1 meter, a 120 Newton jack is used.
