The setting screw in the hinges GN 437 allows the mobility of the hinge to be changed This also generates a constant braking torque adjustable across the whole of the rotating range. The rotation of doors and flaps is so inhibited, also preventing the inadvertent movement.

The friction torque is accomplished by interlocking two slim friction cones. The large friction surface and the hard-wearing plastic of the friction cones guarantee a long service life with only slight reduction in the friction torque over time. This can be re-adjusted, if necessary, with the setting screw.

Owing to the structure and the prestress of the friction cones, the hinge has virtually no radial play and no play at all in axial direction.
