Germany-based solar mounting technology provider K2 Systems has introduced new CrossHook roof fasteners.
Following the launch of the new K2 CrossHook 3S in January, the company now offers the K2 CrossHook 4S, a new variation of the 3S. The roof fastener is height-adjustable in three steps and offers a two-step adjustment of the bracket height. Both the K2 CrossHook 4S and the K2 CrossHook 3S are suited for many different types of tiled roofs with rafter widths 36 mm and up, the company says.
Additionally, K2 Systems has introduced two aluminium roof fasteners, the K2 CrossHook 1F and 2F, which are suitable for many different types of flat-tiled roofs. The 2F can be adjusted up to 30 mm at the bracket, the company adds.
