Description
The IronRidge XR-100-168M-US is a heavy-duty 14-foot (168″) mounting rail designed for use with IronRidge XR flush-mount solar racking systems. Manufactured from high-strength 6000-series aluminum, this rail provides exceptional structural support for residential and commercial solar installations. Its signature curved rail profile enhances structural rigidity, helping resist uplift, prevent buckling, and efficiently transfer loads into the building structure.
The XR100 rail system is engineered to support a wide range of wind and snow loads while allowing spans up to 8 feet between attachments, reducing roof penetrations and installation time.
