The S-5!® S-5-B clamp ("B" is for Brass) is designed specially for double-folded 16 & 20-oz COPPER standing seam panels.

S-5!® standing seam clamps are designed to affix directly to the vertical seams of the metal panels without penetrating the seam by tightening the included round-point, stainless steel setscrews to the specified tension.

All S-5!® standard clamps have undergone rigorous load testing through parallel-to-seam (along the seam or drag load) testing.
