Scharnier met instelbare frictie

The actuating torque of the hinges GN 233 can be adjusted via a setting screw, allowing doors and flaps to be kept open or partially open or closed. Endurance tests have shown that the friction torque has not changed even after 60,000 opening / closing cycles (at 0.8 Nm tightening torque of the setting screw). The hinges comply with flammability category UL 94-HB.
