The S-5 CorruBracket is also available for corrugated profiles but a weatherproof penetration into the purlins will be required to hold the bracket to the roof. Butyl sealant protects the metal roof from any water ingress.
The S-5 range of roof clamps and brackets are so strong they are even approved as a secure anchor point for working at heights safety purposes.
GRipperFix can also be fixed directly to profiles such as Trimdek using self-piercing fasteners. Self-drilling fasteners means there is no drilling swarf or rust and the GRipperFix is guaranteed for 25 years.
