The collector is made of extruded aluminum.
The top and bottom extrusions carry a base channel, in which a heavy secure aluminum fixture is located to anchor the collector to your roof. This anchor slides into place and is properly secured.
The collector’s base is secured to roofing or rafters, to resist uplift winds. It’s designed to be attached to all roofing materials.
