GN 437.3 Hinges with a spring-loaded return allow doors to be automatically opened and closed by means of the torsion spring.

The return torque varies with the hinge opening angle. Endurance tests have shown that the torque does not change even after 100,000 opening / closing cycles.

The following table shows the relationship between the opening angle and return torque.
