The roller blind EOS®500 metal clutch appeals through an intelligent, patented technique, wrapped in a noble design. The durable zamac housing with polished finish contains a chain drive unit, which, despite a high holding torque, excels in maximum operating comfort. Two-component plastic parts on the inside allow for a high sound absorption. The chain drive unit is installed over two pins, which grasp into designated bracket holes. An extra spring loaded axial pin prevents dislocation.
