Hubbell HGBL04SF Grounding and Bonding, #4 1/4" ID Compression Lug

Ensure dependable grounding for security, surveillance and IT infrastructure with the Hubbell Premise Wiring HGBL04SF compression grounding lug. Designed as a grounding and bonding lug, it creates low-resistance electrical connections that protect monitoring, access control and networking equipment from fault conditions and interference. The long-barrel design provides superior conductor engagement for #4 AWG conductors, while the 1/4" ID single-hole, 90° configuration simplifies routing in tight enclosures. Constructed from solid copper and tin-plated for corrosion resistance, this lug maintains conductivity and mechanical integrity over time. An integrated inspection window gives installers a fast visual confirmation of full conductor insertion, reducing callbacks and improving field QA. The HGBL04SF is die-index traceable when compressed with the correctly sized die, enabling repeatable crimps and compliance with installation standards. Ideal for commercial security panels, CCTV power systems, and backbone grounding in network rooms, this lug helps you achieve reliable bonds where it matters most. Add the Hubbell HGBL04SF to your parts inventory for consistent grounding performance — order now to streamline installations and protect critical systems.
