Rotary torque hinge Rotary torque hinge is a door hinge with many advantages, the rotation angle is large, which can reach 360°. At the same time, the rotary torque hinge also has the same advantage of being stuck at any angle as the torque hinge, and more people prefer the rotary torque hinge than the torque hinge. 3.
