Ironridge Mill Bonded Structural Splice XR1000-BOSS-01-M1

The IronRidge XR1000-BOSS-01-M1 is a Bonded Structural Splice (BOSS) designed to connect two IronRidge XR1000 mounting rails while maintaining both structural strength and electrical bonding. This splice creates a seamless internal rail connection that allows installers to extend rail lengths for large solar arrays while preserving system integrity.

The BOSS splice features an integrated bonding spring with teeth that bite into the aluminum rail, creating a secure electrical bond that meets UL grounding requirements without additional grounding hardware. Its tool-free installation and single-piece design help reduce installation time while ensuring reliable mechanical and electrical connections across the solar mounting system.

Key Technology

• BOSS Bonded Structural Splice Technology
  Provides a strong rail-to-rail structural connection while maintaining electrical bonding across the mounting system. 

• Tool-Free Installation
  Single-piece splice installs directly inside XR rails with no tools, hardware, or assembly required.

• Integrated Grounding
  Built-in bonding spring teeth penetrate the aluminum rail surface to create a continuous electrical grounding path. 

• Flexible Placement
  Splices can be placed anywhere along the rail span except the outer cantilever, allowing flexible system design. 

• Hidden Internal Connection
  Internal splice design provides a clean rail appearance and strong mechanical connection.

Best Uses

• Commercial Solar Installations
  Extends XR1000 rail runs for large rooftop solar arrays.

• Utility-Scale Solar Systems
  Maintains strong structural connections across long mounting rail spans.

• High-Load Solar Mounting Systems
  Designed for heavy-duty XR1000 rails used in high wind and snow load environments.
