Friction Hinge

What is a Friction Hinge?

Definition of Friction Hinge in Construction
Friction hinge is a hinge that does not allow the panels, windows or doors to swing freely. There is friction within the hinge assembly that is controllable and is used to slow the opening of a free opening door or window or force the operation of the door and window to be by the individual opening or closing the element being hinged. Although feeling as though the hinge may require lubrication, the friction hinge has many uses and is commonly used to prevent too quick an opening and closing or accidental opening and closing of doors and windows. There are friction hinges that can be adjusted, usually by tightening of loosening a hex nut on the top of the hinge pin itself. This adjustment is similar to the adjustment of a spring hinge.
