Ironridge Grounding Lug Low Profile IR-XR-LUG-04-A1

The IronRidge XR-LUG-04-A1 Low Profile Grounding Lug is designed to provide a reliable equipment grounding connection within compatible IronRidge solar racking installations. Its compact lay-in style makes it easy to integrate into the grounding path while maintaining a low-profile installation.

The grounding lug accepts copper grounding conductors in the 4–10 AWG range and uses a tin-plated aluminum lug body with stainless steel hardware for durable electrical and mechanical performance in PV mounting applications. 

The complete assembly includes the grounding lug, conductor clamping bolt, flange hex nut, and T-bolt mounting hardware, providing the primary components required for installation onto a compatible rail or mounting surface.

Key Technology

• Low-Profile Lay-In Design
  Compact grounding lug design helps provide a clean, streamlined grounding connection on compatible solar racking systems.

• 4–10 AWG Wire Range
  Designed to accept grounding conductors ranging from 4 AWG through 10 AWG.

• Tin-Plated Aluminum Lug
  The grounding lug body is manufactured from tin-plated aluminum with a clear matte finish.

• Stainless Steel Hardware
  Included bolts and flange nut are manufactured from 300 Series stainless steel for durable fastening performance.

• Lay-In Conductor Installation
  The open lug geometry allows the grounding conductor to be positioned directly into the lug before tightening the clamping hardware.

• Complete Grounding Assembly
  Includes the low-profile lug, conductor bolt, flange nut, and T-bolt mounting hardware shown in the IronRidge cut sheet.

Best Uses

• Solar Racking Grounding
  Ideal for establishing an equipment grounding connection on compatible IronRidge PV mounting systems.

• Grounding Conductor Termination
  Provides a secure termination point for grounding conductors between 4 and 10 AWG.

• Low-Clearance Installations
  The low-profile design is useful where minimizing protruding hardware is important.

• PV Array Bonding Applications
  Suitable as part of the grounding and bonding architecture of compatible rooftop or ground-mounted PV systems.
