In 2010, SnoBlox Snojax began selling the patented Universal RoofClamp™, a standing seam clamp for accessory attachment on metal roofing. Paul Riddell of Action Manufacturing LLC invented it. Paul is the son of Dick Riddell, one of the inventors of the first standing seam roof clamp patented in 1993. This revolutionary universal fit roof clamp product attaches almost anything to a standing seam roof. With these clamps, installers can secure satellite dishes, roof walkways, conduits, or HVAC lines. RoofClamp can also be used to attach signs or awnings. The RCT model fits over 95 percent of the standing seam panels on the market, so there is no need to stock the many clamp sizes that some other manufacturers require. The aluminum RoofClamp™ utilizes three stainless-steel cup-tipped screws that do not pierce or penetrate the panel; therefore, it will not damage the panel or void the panel manufacturer's warranty.
