Ironridge Mill Bonded Structural Splice XR100-BOSS-01-M1

The IronRidge XR100-BOSS-01-M1 is a BOSS (Bonded Structural Splice) designed to securely connect two IronRidge XR100 mounting rails while maintaining both structural integrity and electrical bonding. This splice creates a seamless internal rail connection that allows installers to extend rail runs for larger solar arrays without additional grounding hardware.

The BOSS splice features integrated bonding springs with teeth that bite into the aluminum rails to create a continuous electrical path, ensuring compliance with grounding and bonding standards. Its single-piece design requires no tools, assembly, or additional hardware, helping speed up installation and simplify solar racking system assembly.

Key Technology

• BOSS Bonded Structural Splice
  Creates a strong mechanical connection while maintaining electrical bonding between XR rails. 

• Integrated Bonding Springs
  Bonding teeth penetrate the aluminum rail surface to create a continuous grounding path that meets UL standards. 

• Tool-Free Installation
  Single-piece design installs quickly without tools, hardware, or additional assembly steps. 

• Flexible Splice Placement
  Splices can be installed anywhere along the rail span except the outside cantilever.

• Hidden Internal Rail Connection
  Internal splice design keeps connections concealed while maintaining strong structural performance.

Best Uses

• Residential Rooftop Solar Systems
  Extends XR100 rail lengths for flush-mounted photovoltaic arrays.

• Commercial Solar Installations
  Supports larger solar systems requiring longer mounting rail runs.

• High-Strength Rail Connections
  Maintains structural and electrical continuity across solar racking systems.
