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

Frequently Asked Questions
Still deciding if a Butler building is right for your project? Here’s what most builders ask us before they get started.
Still have questions?
Talk to a real person. Call our Pro Desk Expert Line or request a callback.
What makes a Butler building different from other metal buildings?
Butler has been engineering steel buildings for over 125 years, and AM Star is an authorized Butler distributor, not a reseller of generic components. Every building you get through us uses genuine Butler engineered parts, backed by Butler’s manufacturing standards.
Can I customize the size and layout of my building?
Yes. Butler buildings are engineered to your exact specifications, size, use, and site requirements, whether that’s a small workshop or a large industrial facility. Our team works with you from initial design through structural engineering to make sure it fits your project.
How much does a Butler building cost?
Pricing depends on size, building type, durability grade, and site conditions, so there’s no single number that fits every project. Request a quote and we’ll get you accurate pricing fast, tailored to your specific building.
How long does the process take, from quote to finished building?
Timelines vary by project scope and current fabrication schedules. Once you request a quote, we’ll give you a realistic timeframe based on your specific building and location.
Do you handle engineering and permitting?
Yes. Every Butler building is engineered to meet local codes and structural requirements, with stamped drawings provided for permitting, backed by Butler’s manufacturing standards.
What's the difference between a Butler building and a barndominium?
A barndominium is one type of building you can build using Butler’s steel building system, combining residential living space with a metal building structure. It uses the same engineered components and durability standards as our other building types.
What if I'm not building new, I just need parts or repairs?
We also supply genuine Butler parts and components for repairs, replacements, or expansions, no need to order a full building. Browse our parts catalog or contact us directly.
How do I get started?
Request a quote and tell us about your project, building type, size, and timeline. We’ll follow up with accurate pricing and next steps, no pressure, no runaround.
