VersaBracket™ can be used to mount almost anything to an exposed-fastened roof system and is compatible with almost any trapezoidal exposed?fastened profile. No messy sealants to apply! No chance for leaks! The VersaBracket comes with factory?applied butyl sealant already in the base, and the S-5!® patented reservoir conceals the sealant from UV exposure, preventing drying and cracks. The VersaBracket-67 mounting face has no holes or slots; thus, ancillary items are typically secured using self-tapping screws.
