Functional hinge

With GN 437.2 Hinges, doors and covers can be secured at any desired angular position. In its rest position, the hand lever is not connected to the locking thread of the hinge axis, i.e., it can be freely rotated. The serration only engages when the handle is pressed down, allowing the hinge to be clamped. This prevents the engagement from releasing unintentionally. It additionally ensures that the hand lever does not hinder the movement of the door or cover. To adjust to the door or cover, the clamp must be disengaged before the hinge can be swung into the new position.
