1-1/2" TB-Style Conduit Body

The Killark TB-style conduit outlet body provides a 27.0 cubic inch interior for pulling and splicing conductors in 1-1/2 inch trade size rigid or IMC conduit. It is built from iron with a gray powder-coated Duraloy 7 finish for corrosion resistance in industrial and commercial electrical installations.

Sustained load behavior

The iron construction and powder-coated finish maintain structural integrity and thread engagement during continuous exposure to vibration, temperature cycling, and mechanical stress typical of heavy-duty conduit runs. The flat back design distributes mounting loads evenly across the supporting surface without deformation over time.

Installation and common issues

Threaded hubs accept standard 1-1/2 inch conduit connections and compatible covers such as the 570 series seal the body after wiring. Installers must verify that the 27 cu in capacity meets fill requirements for the specific conductor count and size used, as exceeding the rated volume is the primary cause of code violations.

Questions about this item

Does the Killark TB conduit body generate any noise or heat when energized continuously?

The iron body is a passive fitting with no moving parts or electronics, so it produces no audible noise and no measurable heat during continuous operation.

What conduit, fittings and covers must I already have to install this 1-1/2" TB outlet body?

You need 1-1/2" IMC or RMC conduit, matching threaded couplings or nipples, and a compatible cover such as the 570, 570C, 570CG, 570CGSA, 570CSA, 570G, 570GSA or 570SA.

Will the 27 cu in capacity and threaded hubs work with older rigid metal conduit already in the building?

Yes, the 1-1/2" threaded hubs accept existing RMC and IMC, and the 27 cu in volume meets code for splicing or pulling conductors in legacy installations.
