With the Duraklick ECO, we can offer you a very economical and cost-effective alternative to our SR system. It consists of bottom rails and the module clamps; there are no spoilers or wind screens. However, the reduced aerodynamics require a slightly higher ballast. This system is also distinguished by its outstanding Duraklick system properties, such as simple installation, our click system and a self-supporting, lightweight aluminium design. The ECO system is available with module slopes of 10°, 15° and 20°.
