Meet the S-5-H clamp—the horizontal-seam edition designed for standing seam roofs. It’s the secure, easy-to-install mounting solution for professionals and DIYers who need to attach accessories to seams that aren’t fully closed.

Key Features & Design

• For standing seam panels with horizontal seam orientation (single-folded). The S-5-H is built to work where the seam runs horizontally.
• Accommodates horizontal seams not fully closed. Perfect when the seam isn’t completely sealed, without compromising integrity.
• Two-piece design for versatile placement. Attaches anywhere along the seam length—just place the clamp, slide the insert piece into place, and tighten the setscrews.
• Wide seam compatibility. Insert allows clamp to fit over wider horizontal seams up to 0.75” (19 mm).
• Vertical-leg attachment on horizontal seam. The clamp is unique in allowing attachment to the vertical leg of the seam for added versatility.
• Hardware included for quick installation. Two T-30 Torx round-point setscrews (Torx bit tip provided) and one M8 bolt included. After installation, affix ancillary items using the top stainless steel bolt provided.
• Heavy-duty compatibility. Ideal for use with S-5! ColorGard® snow retention system and other demanding applications.
• Variants available. The S-5-H clamp is also available in the smaller S-5-H Mini.
• Warranty you can rely on. S-5! offers a Lifetime Product Defect Warranty and a ColorGard Snow Retention System warranty of 30 years or the life of the roof, whichever comes first.
