The tool-free pre-installation is a particular advantage of the 435. In the lower section of the roof tile, directly on the side lock, it secures three roof tiles simultaneously, like all other side lock clips. This is confirmed by tests according to EN 14437.
High durability of the storm clip is ensured by stainless steel grade 1.4301 (A2) or ZIAL® (Zinc-Aluminium) coated surfaces. The clip is available for all common batten sizes, in various dimensions with a round and an angular hook.
