The S-5-U (“U” stands for Universal) is a popular and versatile clamp. Its generous dimensioning accommodates a majority of the standing seam profiles in North and South America—including most structural and architectural profiles.
The U is used on vertically-oriented seams and rotated 90 degrees for use on many horizontal seam profiles.
Although there are more cost-effective S-5! options, the advantage of the U clamp is its versatility. Check out more cost-effective alternatives (S-5-V, S-5-E or S-5-S for vertically-oriented seam applications and the S-5-H 90 and S-5-H for horizontal applications).
The U Mini clamp is a more economical solution for lighter-duty attachments where Herculean holding strength is not required.
All standard and Mini clamps undergo rigorous load testing. Negative load normal-to-seam testing (pull-up) is performed on all Mini clamps, and parallel-to-seam testing (drag load) is performed on all standard clamps.
