GLS11 Crouse-Hinds 5" Grounding Bushing — Threadless, Aluminum Lug #3/0–6 AWG

GLS11 Crouse-Hinds 5" Grounding Bushing — Threadless, Aluminum Lug #3/0–6 AWG

Need to bond and ground a 5" rigid or IMC run? The Crouse-Hinds GLS11 slips onto threadless conduit and locks down with a single set screw, so you get a clean grounding termination without fighting threads in tight gear. The aluminum lug lands a copper or aluminum ground conductor anywhere from #3/0 down to #6 AWG, and the insulated plastic throat keeps your conductor insulation off the metal edge on the way through.

It's a malleable iron body with a zinc-plated finish and external stainless hardware, rated 105°C, UL listed and cUL/CSA marked under File E6225 — built to hold up where you're installing it.

Common Applications

• Grounding 5" RMC and IMC at panels, switchgear, and service entrances
• Bonding conduit to ground bars and enclosures
• Commercial, institutional, and industrial conduit runs
• Anywhere you need an insulated-throat ground bushing on threadless 5" conduit

FAQ

Does the GLS11 fit threaded or threadless conduit? Threadless. It's the set-screw type and ships with one set screw to lock it onto 5" rigid/IMC.

What ground wire can I land in it? The aluminum lug takes copper or aluminum from #3/0 to #6 AWG.

Is the lug rated for aluminum conductors? Yes — the aluminum lug is rated for both copper and aluminum grounding conductors.

Will it stand up to a rough install? The body is malleable iron with zinc plating and external stainless hardware, rated 105°C.

Is it code-listed? Yes, UL listed and cUL/CSA certified for Canada under File E6225, for NEC/CEC grounding in ordinary locations.

Need a bigger conductor range? Step up to the GLS11 250 (250 kcmil–6 AWG aluminum lug) or GLS11 250C (copper lug). This GLS11 is the #3/0–6 AWG aluminum-lug version.
