Thomas & Betts Conduit Body, Aluminum, C-Type, FM7

Six trade sizes: 1/2, 3/4, 1, 1-1/4, 1-1/2 and 2 inch. The part numbers run C17SA (1/2"), C27SA (3/4"), C37SA (1"), C47SA (1-1/4"), C57SA (1-1/2") and C67SA (2"). Match the size to the conduit run it is going into, since the hubs are threaded for that trade size only.

A Type C body is the straight-through pull fitting. Both hubs are in line with each other, so it gives you an access opening to pull conductors on a long straight run without changing direction. If you need to turn a corner, that is an L-type (LB, LL, LR) rather than a C; if you need a branch, that is a T-type. The Thomas & Betts C7SA bodies are the straight version.

For an EMT run, the Crouse-Hinds C15MTC-6 is the one to look at; it is a Condulet Series 5 Type C outlet body built as a combination EMT body. The Thomas & Betts C-series bodies (C17SA through C67SA, 1/2 inch to 2 inch) are threaded bodies intended for threaded conduit, so an EMT run would need connectors or an EMT-specific body instead.

The closest peer is the Crouse-Hinds C15MTC-6 Condulet Type C conduit outlet body, part of the Condulet Series 5. Both are Type C (straight-through, single-opening) conduit bodies for 1/2 inch trade size. The difference is the hub style: the Thomas & Betts C17SA takes threaded rigid/IMC conduit, while the C15MTC-6 is a combination EMT body, so it accepts EMT as well. Match the hub type to the raceway you are actually running before you swap one for the other.

Sand cast aluminum. That keeps the body light and corrosion resistant for outdoor and damp exposed runs, but avoid it where the environment is hard on aluminum, such as direct contact with concrete, embedded chlorides, or heavy chemical exposure, where a cast iron or malleable body is the better call.

The C7SA bodies are sold as the body itself. Covers and gaskets for conduit bodies are separate line items, so order a cover sized to the same trade size as the body (1/2 through 2 inch here) and a gasket if the location is wet or damp.

The Crouse-Hinds C15MTC-6 is a single 1/2 inch Condulet Series 5 Type C body. If you want one family across a run that steps up in size, the Thomas & Betts C-series spans 1/2 inch, 3/4 inch, 1 inch, 1-1/4 inch, 1-1/2 inch and 2 inch as C17SA, C27SA, C37SA, C47SA, C57SA and C67SA, all sand cast aluminum, so the body style stays consistent as the trade size changes.

Yes. The C7SA family covers 1/2, 3/4, 1, 1-1/4, 1-1/2 and 2 inch in the same sand cast aluminum Type C configuration, so one series and one cover style carries the whole range of runs in a building. Part numbers follow the pattern C17SA through C67SA by size.

The Thomas & Betts C17SA family is sand cast aluminum. The Crouse-Hinds C15MTC-6 is identified as a Condulet Series 5 Type C conduit outlet body, and Condulet bodies are specified by series rather than by a shared material with the T&B line - so confirm the material you need for the environment and pick the body accordingly rather than assuming the two are interchangeable on corrosion exposure.
