S5! Seam Clamps & PV KIts

S-5! are the market leaders when it comes to seam clamps & PV kits for metal roofs. S-5! clamps attach to the panel seam by the tightening of two "bullet-nosed" stainless steel setscrews against the seam material. (This is usually done with an industrial grade screwgun.)
 
The setscrews compress the seam material against the opposite wall of the clamp. They will "dimple" the seam material, but will not penetrate it. Threaded holes in the clamp (and stainless hardware provided) enable the easy attachment of various ancillary items to the clamps.

S5! PV Kit

In most cases, the savings in time and materials is sufficient to pay for the entire S-5-PV Kit and clamp setup! The S-5-PV Kit continues to be the easiest, most cost-effective way to install solar panels directly to standing seam metal roofs and remains the most popular choice worldwide.
