RibBracket IV can be used to mount almost anything onto the most common exposed-fastened, trapezoidal roof profiles marketed in North America today. No messy sealants to apply! No chance for leaks! The RibBracket comes with a factory-applied EPDM rubber gasket seal already on the base, and the S-5!® patented reservoir conceals the EPDM from UV exposure, preventing drying and cracks. Installation is simple! The RibBracket is mounted directly onto the crown of the panel, straddling the profile. No surface preparation is necessary; simply wipe away excess oil and debris, align, and apply. Secure through the pre-punched holes using the appropriate fasteners or Bulb-tite rivets for the supporting roof material. RibBracket is the perfect match for our S-5-PV Kit, or any other ancillary application, without worrying about cold bridging! RibBracket is extremely economical and facilitates quick and easy installation. The slotted top hole, which accommodates standard M8 nuts and bolts, simplifies alignment and maximizes flexibility in attaching ancillaries. Other RibBracket models: RibBracket I, RibBracket II and RibBracket III. RibBracket IV can be used to mount snow retention systems like S-5! ColorGard, solar racking systems and S-5! PV Kit 2.0, as well as  a host of other roof top mounted products. All pre-punched holes must be used to achieve tested strength. RibBracket includes four (4) 1/4-14 screws for mounting, and one (1) M8 hex nut.
