Why Choose the S-5-USF Mini Clamp for Your Project?

For those times when a nut and bolt provides the ideal connection to a standing seam clamp, the S-5-USF Mini (“USF” for Universal System Flange) is an economical, non-penetrating standing seam metal roof (SSMR) clamp for most vertically-oriented seam profiles.

With a slotted hole in the flange for minor adjustment, the USF is ideal for walkways, module-level power electronics, bottom-mount solar rails and a host of other utility mountings.

Stainless steel lock-nuts and several bolt sizes are sold separately.

The USF Mini has a single setscrew for medium or light-duty applications, such as satellite dish and other rooftop utility mounting.

Please refer to the load testing of the S-5-U Mini for holding capacities of this clamp on different materials and seam specifics.

Choose the USF Mini to mount a variety of utilities to your snap seam and double-folded, standing seam metal roof with nominal seam thickness ≤ 0.47” (12 mm)

For more traditional double-folded seam dimensioning, the S-5-EF provides better economy than this clamp. Also see the S-5-Flange Adapter to turn any S-5 clamp into a flanged component.
