The S-5 U-Mini is a medium-duty, non-penetrating seam clamp. It is a bit shorter than the S-5 U and has one setscrew rather than two. The Mini is the choice for attaching all kinds of rooftop accessories: signs, walkways, satellite dishes, antennas, rooftop lighting, lightning protection systems, solar arrays, exhaust stack bracing, conduit, condensate lines, mechanical equipment - just about anything!

Installation is as simple as placing the clamp on the seam and tightening the patented round-point setscrew to the specified tension. Then, affix ancillary items using the bolt provided. Go to for information and tools available for properly attaching and tensioning S-5! clamps. Thanks to patented round-tip setscrews, S-5! clamps do not pierce metal roof paneling, thereby protecting roof coatings and weather tightness warranties.
