Due to the constant braking force of the hinge, your heavy commercial doors will close at a controlled speed every time. You should let the door close on its own without any additional hand force to avoid accelerated closing speed. \u003c\/span\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eOn the other hand, Hydraulic Hybrid hinges are soft-closing hinges ideal for quiet closing applications.
