Why S-5!® clamps?

Because S-5! clamps attach almost anything to standing seam metal roofs without piercing the panel! S-5! clamps are available for virtually any panel profile on the market.

Because S-5! clamps attach almost anything to standing seam metal roofs without piercing the panel! S-5! clamps are available for virtually any panel profile on the market—architectural and metal building panels. S-5! clamp technology involves gripping the seam in such a way that there is no penetration to the panel material. We utilize , round-point setscrews for attachments that are specially made only for the S-5! system. S-5! never uses “cup-point” screws like all the copycats do. Such a screw point cuts through the paint and protective coating of standing seam panels, causing corrosion and voiding warranties.

We have done 1,000-hour ASTM B-117 salt fog testing of our attachment to be sure that it causes NO CORROSION on painted Galvalume® or galvanized panels. All related S-5! hardware is noncorrosive 300 series stainless, not plated steel. The tenacity of the S-5! method of attachment is thoroughly tested and unequaled by other products.

Holding strength of S-5! varies on different seam profiles, material types and gauges—and we have tested our products on all those different panel seams, doing hundreds of independent laboratory pull tests.
