Description: Material: The adjustable control hinge is made of plastic, which is lightweight and durable, corrosion-resistant, has good insulation properties and has a long service life.Damping Switch: There is an adjustable damping device inside the hinge, which can stop positioning at any angle and adjust the torque. It can provide a buffering effect when the door leaf is opened or closed, making the opening and closing process smoother and quieter.Easy Installation: Determine the installation position of the hinge, fix the hinge on the door leaf and door frame with self-tapping screws (not included), pay attention to keep the hinge axis parallel to the edge of the door leaf and door frame. Adjust the damping adjuster to adjust the resistance that suits you.
