IronRidge XR100 204" (17 Foot) Mill Rail XR-100-204M

The IronRidge XR-100-204M is a heavy-duty 204-inch (17 ft) solar mounting rail designed for use with IronRidge XR flush-mount racking systems. Built from high-strength 6000-series aluminum, the XR100 rail provides excellent structural strength while remaining lightweight and corrosion resistant for long-term outdoor use.

The XR100 rail features IronRidge’s signature curved rail profile, which increases rigidity and resistance to uplift while helping distribute loads efficiently across roof attachments. This design allows spans of up to 8 feet between attachments, reducing the number of roof penetrations and simplifying installation for residential and commercial photovoltaic arrays. 

Key Technology

• XR100 Structural Rail Design
  The engineered curved rail profile improves structural strength and helps resist uplift and buckling during extreme weather conditions. 

• Heavy Load Capability
  Supports demanding wind and snow load conditions commonly encountered in residential and commercial rooftop solar installations.

• 6000-Series Aluminum Construction
  High-strength aluminum alloy ensures durability, corrosion resistance, and long-term structural performance. 

• Extended Rail Length
  The 17-foot rail enables longer module rows, reducing the number of rail splices required during installation.

• IronRidge XR System Compatibility
  Works seamlessly with IronRidge clamps, bonded splices, grounding hardware, and roof attachments.

Best Uses

• Residential Rooftop Solar Systems
  Provides the structural backbone for flush-mounted PV systems using IronRidge racking.
