CorruBracket™ can be used to mount almost anything to corrugated metal roofing. CorruBracket is compatible with 7/8" and 3/4" U.S. corrugated profiles. No messy sealants to apply! No chance for leaks! The CorruBracket comes with factory-applied butyl sealant already in the base, and the patented reservoir conceals the sealant from UV exposure, preventing UV degradation.
