The TonKor Adjustable Tilt Legs Set combines an adjustable rear leg with two preset tilt positions, 15 and 30 degree, and a matching adjustable front leg to create a defined mounting plane on color steel metal roofs. Installers mark the layout line, fasten the rear leg at the required tilt, set the front leg height to match the plane, then attach the rail and clamp set to complete module fastening. This format keeps the tilt consistent across bays, improves visual uniformity, and supports tidy cable routing. Pairing should be confirmed against the project bill of materials and the selected rail and clamp family.
