S5! clamps are made for various standing-seam metal roofing, and can be used to mount rails or PV modules directly, as shown.
Metal Roof Innovations Ltd.’s S5! clamps don’t require any roof penetrations, nor do they penetrate the seam of the roof, but clamp on by means of stainless steel setscrews. The clamps can be mounted from the side of the seam or from the top, and are available with various set-screw hole configurations and clamp profiles to suit variations in standing seams. Depending on the thickness of the metal, tightening specs vary for the setscrews: 115 inch-pounds (for 24-gauge metals) or 150 inch-pounds (for 22-gauge steel). Some S5! installations don’t need rail, as the module frames are supported by the top platform of the S5! clamps, and mid- and/or end-clips are bolted directly to the clamp. Other installations use the S5! clamps to mount standard rails.
