BUTLER S-5 SOLAR PANEL CLIPS
The Industry Standard Solar Panel Clip for Every Buildings
The Perfect Solar Panel Clip for Every Buildings
The RibBracket I, II, IV, and V is designed for use with the PVKIT® in rail-free solar mounting systems. Available in five sizes, it offers an economical, sheeting-only attachment that can be installed anywhere along the roof ribs.
Because it is not tied to the building substructure, it allows flexible module placement across the entire roof. It also supports mounting for microinverters and other module-level electronics.
Its angled design converts wind uplift into shear force, delivering strong pull-out resistance. A slotted top hole allows easy alignment and spacing adjustments, while the 4” air gap improves airflow for cooling and simplifies installation. Integrated wire management keeps the system clean and organized.
Every building is engineered to handle solar panel loads with confidence, ensuring secure integration and lasting structural integrity.


RibBracket I, II, IV, and V Works for the Following Roofs:

- Exposed-Fastened
- Trapezoidal
