2-1/2 in Threaded Conduit Bushing

The L.H. DOTTIE GBL250 is a zinc-plated aluminium bushing designed for 2-1/2 inch threaded conduit systems. It provides a smooth bearing surface to protect cable insulation during pulling operations. The fitting connects directly to threaded rigid or IMC conduit without additional hardware. Electrical contractors use it to complete raceway installations in commercial and industrial environments.

Suited for threaded metallic raceways

This bushing suits installers working with 2-1/2 inch threaded rigid metal conduit or intermediate metal conduit who need code-compliant cable protection. It is not for non-threaded conduit systems such as EMT set-screw or compression couplings. Installers requiring insulated throats or plastic bushings for specific environment ratings should select a different fitting type.

2-1/2 in trade size defines fit

The 2-1/2 inch trade size is the single specification that determines compatibility with the conduit run. Only conduit and fittings sharing this exact trade size will thread together correctly. Verifying the raceway size before ordering prevents mismatched components on the job site.

Questions about this item

What size threaded conduit does the 2-1/2 in bushing fit?

The bushing is sized for 2-1/2 in threaded conduit, matching standard trade-size fittings for that diameter.

Can the zinc-plated aluminum bushing be used with existing steel conduit?

Yes, the zinc-plated aluminum threads mate with standard steel conduit threads of the same trade size.

How can I confirm the bushing is seated correctly after installation?

The bushing should sit flush with the conduit end, threads fully engaged, and the cable should pass through the smooth bore without snagging.
