XR Rails® are the structural backbone of IronRidge® pitched, flat and ground-based arrays. Their signature curve helps them to resist uplift, protect against buckling and safely and efficiently transfer loads into the building structure.

Their superior spanning capability requires fewer roof attachments, reducing the number of roof penetrations and the amount of installation time. Each size supports specific design loads, while minimizing material costs. Depending on your location, there is an XR Rail® to match.



XR100® is the ultimate residential mounting rail. It supports a range of wind and snow conditions, while also maximizing spans up to 8 feet.
