Residential Metal Roof
Mounting hardware for solar on a standing-seam or exposed-fastener metal roof, built around the S-5! clamp system: the clamp grips the seam without a single hole in the roof, and the PVKIT grabs hold the panel to the clamp, so most metal-roof arrays go up with no rails at all.

Pick the clamp by the seam profile: S-5-S for snap-together vertical seams, S-5-V and S-5-U for mechanically folded seams, S-5-E for Butler-style double-fold, S-5-H for horizontal seams, S-5-T for T-shaped seams, S-5-Z for round bulb seams, S-5-N 1.5 for nail-strip, S-5-B for copper. For exposed-fastener and corrugated roofs use the CorruBracket, RibBracket or SolarFoot instead. Then add a PVKIT MidGrab between panels and an EdgeGrab at each edge; the grabs carry the UL 2703 ground path.
The Complete Railless Roof Mount Package bundles the clamps and grabs for a typical array. Tell us your roof profile and panel count and we will put the exact kit together. S-5! installation sheets and torque values are on each product page.
