GLS11 Crouse-Hinds 5" Insulated Grounding Bushing — Fits Rigid & IMC Conduit

GLS11 Crouse-Hinds 5" Insulated Grounding Bushing — Fits Rigid & IMC Conduit

Trying to figure out which grounding bushing fits a 5-inch conduit? The Crouse-Hinds GLS11 is the part you're likely after. A grounding bushing is the fitting that lets you connect a ground wire to your conduit and protect the wire where it enters — and this one is sized for 5" rigid or IMC conduit.

It uses a threadless, set-screw design, so it slides on and tightens in place with the included screw (no threading required). The aluminum lug accepts a copper or aluminum ground conductor from #3/0 to #6 AWG, and the plastic-lined "insulated throat" keeps the wire from chafing on the metal edge. The body is durable malleable iron, it's rated to 105°C, and it's UL listed and CSA-certified for Canada under File E6225.
