S-5-B Clamp

The S-5-B is made of brass (a copper-zinc alloy) to ensure metallurgical compatibility with copper roofs. Using aluminum on a copper roof causes galvanic corrosion, which degrades both the clamp and the roofing material over time.

No. Like all S-5! clamps, the S-5-B Mini uses a patented round-point setscrew that 'dimples' the seam without piercing the metal, protecting your roof's weathering membrane and maintaining its warranty.

The S-5-B Mini is shorter and utilizes a single setscrew for medium-duty attachments like solar arrays and satellite dishes. The standard S-5-B is longer and uses two setscrews for heavy-duty applications such as snow retention systems.

Installation requires a standard screw gun and a T-30 Torx bit (often included). For load-critical applications, a calibrated torque wrench is required to ensure the setscrew is tensioned between 130 and 150 inch-pounds.
