In Part 1 of our three-part series on S-5 Manufacturing, we discussed the history and the relationship between Rob Haddock and Harry Carner. In Part 2, we venture inside the facility to learn more about how those mighty clamps and brackets are actually made. We'll also delve into all of the plant staff - the human kind AND the machine kind.

UL, an abbreviation for Underwriters Laboratories, is a testing and approving organization. Founded in 1894, UL performs safety testing on numerous electrical, mechanical, and chemical consumer and commercial products. Its roots began in electrical and fire safety, but UL now serves other industries and tests hazardous substances, water quality, food safety, and more.
You seem to see it everywhere – that red, black, or white circle with the capital “U” and “L” letters inside. It shows up on various products in our homes and workplaces. You rightly assume that it is important: When something has the UL stamp, it means it has been properly designed and engineered for its specific use. A UL listed mark on a product demonstrates it has been vigorously tested to meet safety specifications determined from the potential and probable hazards of the product. It means the product can be depended on to perform its purpose when needed the most.

Best design and installation practices when using seam clamps to structurally attach PV systems to standing seam metal roofs
Standing seam metal roofing (SSMR) is the most convenient of any roof type for mounting PV modules, either crystalline or thin-film. The seams of SSMR are beam-like elements that not only add stiffness and flexural strength to the roof panels, but also provide expedient attachment points for a PV system. Joining PV modules to this roof type can be done with or without continuous mounting rails using aluminum seam clamps.
Seam Clamps and Mechanical Compression
These clamps anchor to the roof seam by pinching it within the clamp body with round point set-screws that are in no way invasive to the roof. The setscrew forces the metal of the standing seam into a recess in the opposing clamp wall, permanently deforming it in order to establish a mechanical interlock. The clamp body is machined with threaded holes to facilitate anchorage of PV modules or racking components to the clamp.
