The S-5-U Mini is a medium-duty, non-penetrating seam clamp.  (A bit shorter than the S-5-U and having 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!
