Ground-Based System
Mount on all terrains, in no time.
The IronRidge Ground Mount System combines our XR100 or XR1000 rails with locally-sourced steel pipes or mechanical tubing, to create a cost-effective structure capable of handling any site or terrain challenge.
Installation is simple with only a few structural components and no drilling, welding, or heavy machinery required. In addition, the system works with a variety of foundation options, including concrete piers and driven piles. Compatible with soil classes 2-4.
Rugged Construction
Engineered steel and aluminum components ensure durability
UL 2703 Listed System
System and components meet newest effective UL 2703 standard.
PE Certified
Pre-stamped engineering letters available in most states.
Flexible Architecture
Multiple foundation and array configuration options.
25-Year Warranty
Products guaranteed to be free of impairing defects.
Design Assistant
Online software makes it simple to create, share, and price projects.
XR RAILS
XR Rails’ unique curved profile increases structural strength and spanning capability, meaning fewer roof penetrations and more cost-effective designs.
TOP CAPS
Available in sizes that fit either 2” or 3” steel pipe and mechanical tubing, the top cap supports cross pipes with U-bolt hardware.
RAIL CONNECTORS
Attaches and bonds horizontal cross pipes to XR100 or XR1000 Rails. Available for both 2” and 3” sizes.
DIAGONAL CROSS BRACES
Optional assembly kit is for those rare installations that require extra support. Includes the brace, sleeves, and hardware.
UFO & STOPPER SLEEVES
The Universal Fastening Object is a universal, single-piece mid clamp. When combined with a Stopper Sleeve, the UFO functions as an end clamp.
CAMO
This tool-free, universal, invisible end clamp is designed to bond and secure while improving array aesthetics. It comes as one piece, fully assembled.
BONDED SPLICES
XR1000 Rail use our classic Bonded Splices for seamless connections. They come with self-drilling screws to form secure bonding connections. For XR100, the BOSS (Bonded Structural Splice) is now available.
OTHER HARDWARE
All our hardware is designed for single-tool installs, low profiles, and in support of our UL2703 listings: Grounding Lugs, T-bolts, Square-bolts and MI kits.
PIPE & TUBING
Locally-sourced 2” or 3” schedule 40 pipe and mechanical tubing help you save on freight, while still spanning up to 18’ between vertical piers.
Schedule 40 Pipe
- 3” pipe: OD 3.5”, wall thickness 0.216”, 35ksi yield strength
- 2” pipe: OD 2.38”, wall thickness 0.154”, 35ksi yield strength
Mechanical Tubing
- 3” Tubing: OD 3.5”, wall thickness 0.165”, 45ksi yield strength
- 2” Tubing: OD 2.375”, wall thickness 0.109”, 50ksi yield strength
ACCESSORIES
Provide a finished look and support electrical wires. Constructed from UV-stabilized polymers for long-lasting performance: End Caps & Wire Clips.
SPAN AND PIPE CHART
Refer to the following table to see how size impacts the East-West span between foundations. The table complies with ASCE 7-16 structural code. Values are based on 72-cell modules in Wind Exposure Category B.

UFOs are one-size-fits-all, single-piece fasteners that quickly and securely bonds solar modules to XR Rails. They come lubricated and assembled, with a sleek, low-profile design. Simply snapping on a Stopper Sleeve transforms the UFO into an end clamp.
Modules are clamped to XR1000 rails to create a column between the North (high) and South (low) cross pipes. XR1000 rails support up to 5 modules per column in landscape orientation.
Diagonal Braces are optionally available for severe load conditions to provide extra stability in the North-South direction.
