For the latin style constructed roofs, the “fermacoppo” clip is an essential element for the stability, the ventilation and the correct mantle cover maintenance, having at the same time an enduring solution. The Bin Sistemi Srl “fermacoppo” clips typologies have three main categories, depending from the material and the usage functions. The clips are available in stainless steel AISI 304 (with a 3,4x2,2 rectangular section), copper (with a rectangular and strap section) and pre-varnished steel (with a strap section). With a reference to the use functions, we set apart departure and “fermacoppo” clips, and “rompitratta” clips.
