This snow guard is designed to accommodate standing seams of up to 9/32"(0.297" thick) in thickness and suited to heavier gauge metals such as 20 ounce copper, 24 gauge pre-finished metal and products of similar thickness. RT 300 Snow Guards are non-penetrating devices which are secured to the standing seams of metal roofs utilizing stainless steel set screws to clamp them into place. They require no glues or sealants, and will not restrict thermal movement or contribute to unsightly oil-canning. They are particularly suited to double-lock and mechanically seamed metal roofing, and being traditional in design, they are ideal for restoration and preservation work.
It is recommended that the Black E Coat Epoxy snow guards be painted or finished. The E Coat is not a finished coat.
