S-5! RibBracket™ III

Flexible Legs Accommodate Various Trapezoidal Metal Roof Profiles

The RibBracket I-V is used with the PVKIT® for (rail-less) solar PV mounting. This metal roof bracket comes in five different sizes and is an economical, sheeting-only attachment solution that can be placed anywhere along the roof ribs.

RibBracket I-V is not limited to the location of the building substructure, offering infinite flexibility for module placement anywhere on your roof. You can mount microinverters and other module-level power electronics as well.

Angled Attachment to Resist Pull-Out

The RibBracket I-V design converts upward pull from wind uplift into shear, achieving unsurpassed holding strength.

The slotted top hole provides lateral adjustability of the PVKIT for space correction and to easily square up the modules.

RibBracket I-V provides 4” (100 mm) of air space, allowing ample airflow for module cooling and easy access for installation. The part has a channel for wire management.

Which RibBracket I-V is Right for Your Roof Profile?

Trapezoidal profiles vary in angles and dimensions. Most one-size-fits-all solutions offered by others involve top-down fastening, which puts the fastener in direct withdrawal (or pull-out). These pull-out values in sheet metal are extremely low, putting the PV array at risk of blow-off.

The design of the RibBracket I-V places fasteners in shear rather than pull-out. This provides a substantially stronger attachment. These metal roof brackets are therefore specifically designed to accommodate a variety of trapezoidal rib angles and dimensions.

Do not use RibBracket I-V with rails.

S-5! also offers a fully adjustable option that fits all trapezoidal profiles with the same technologies as discussed above, but at a higher cost.
