DOTTIE GBL150 threaded aluminum bushing

The DOTTIE GBL150 is a conduit fitting bushing designed to protect cable insulation where conductors pass through a threaded opening. It suits electricians and installers working with rigid or intermediate metal conduit systems who need a smooth, code-compliant bearing surface at each box or enclosure entry.

Sustained load behavior

Under continuous mechanical stress the aluminum body resists deformation and maintains its internal diameter without cracking. The threaded profile holds firm against vibration and thermal cycling, so the bushing continues to prevent abrasion on long cable runs even after years of service.

Build quality and daily use

Machined aluminum construction provides corrosion resistance and a clean thread finish that engages smoothly with conduit couplings or hub fittings. The 1-1/2 in size matches standard trade dimensions, allowing quick hand-tightening followed by a wrench turn for a secure, flush fit in junction boxes or panelboards.

Questions about this item

Does the aluminum bushing generate noticeable heat when conduit runs continuously?

The threaded aluminum body conducts heat away from cables without adding measurable temperature rise during continuous use.

What conduit size must already be installed for the 1-1/2 in threaded bushing to fit?

It mates with standard 1-1/2 in rigid or IMC conduit threads, so that exact trade size must be present.

Will the GBL150 bushing thread onto older galvanized conduit without cross-threading?

The precision-cut aluminum threads engage cleanly with existing galvanized steel conduit of the same trade size.
