S-5!, a manufacturer of metal roof fastening solutions with non-penetrating solutions, has launched a new electrical conduit clamp for metal roofs.
The CanDuit Clamp secures and supports conduit for cable management and secures “electrical circuits” – the electrical cable that carries power from the main circuit breaker panel to the first electrical box, outlet or switch in the circuit – to the metal roofs of the systems photovoltaic solar panels, in combination with any S-5! clamp or support.
The CanDuit is made of electro-galvanized steel, protecting the clamp from potential corrosion, and is available in 14 different sizes for residential and commercial applications. It is designed with two halves that attach around a pipe or conduit with an EPDM liner pad that protects against abrasion and an M8 threaded stud that allows attachment to S-5! products – providing easy and organized fixing without scratches, corrosion or other damage to the roof.
According to S-5! CEO Rob Haddock, the product was developed in response to customer needs, as the company has apparently been approached several times about solutions for attaching tube-like objects to metal roofs. The relationship between photovoltaic systems and metal roofs is one that S-5! knows well and, according to Haddock, the company jumped at the chance to fill an industry need in its area of expertise.
Solar PV mounting systems for standing seam roof installations should be mechanically attached to panel seams only via cable ties to maintain the design features and warranties of the roof. Additionally, metal roofs will outlast the life of a solar PV system, so it is essential that the mounting system and all attachments protect and maintain the durability of the roof. The CanDuit adapts to this mold for both of these needs, attaching directly and securely to the seams of the roof, preventing any damage that would be caused by movement over time.
