Thomas & Betts CIBC Rigid Conduit Body

It is the cover only, for rigid conduit bodies. You get the stamped aluminum cover plate, not the LB, T, or C body casting itself. If you need the body as well, order that separately.

Both are 1-1/4 inch conduit body covers, so they address the same opening size: the Thomas & Betts CIBC-1 1/4 is a stamped aluminum conduit body cover, and the Arlington Industries 933 is an AnyBODY series LB conduit body cover supplied with a gasket in 1-1/4 inch. The practical difference is that the Arlington 933 is sold as a cover and gasket set for AnyBODY LB bodies, while the CIBC-1 1/4 is the stamped aluminum cover itself. Confirm the cover pattern and screw spacing match the body already in the run before ordering either one, since conduit body covers are not universally interchangeable across manufacturers.

The Arlington Industries 933 AnyBODY LB conduit body cover is supplied as a cover and gasket together in 1-1/4 inch, so the sealing member comes in the box. The Thomas & Betts CIBC conduit body cover is a stamped aluminum cover offered in 1/2 inch and 1-1/4 inch sizes; if your installation calls for a gasket, order the gasket for that body separately. Match the gasket to the body's cover pattern rather than to the cover material.

Use a cover built for that form. The Crouse-Hinds 270 is a Form 7 wedge nut cover in sheet steel, so it is the match for a Form 7 conduit body. The Thomas & Betts CIBC conduit body cover is a stamped aluminum cover offered in 1/2 inch and 1-1/4 inch and is not a Form 7 wedge nut cover, so it should not be substituted onto a Form 7 body even when the trade size agrees.

The CIBC is specified for rigid conduit bodies. Trade size on rigid and EMT is nominal, but the cover must match the body's own cover opening and screw spacing, so buy the cover to suit the rigid body it goes on rather than assuming it drops onto another manufacturer's form.

The CIBC is supplied as a stamped aluminum cover; no gasket is part of it. For a wet or damp location where you need the seal included with the cover, the Arlington Industries 933 AnyBODY cover ships as a cover and gasket set in 1-1/4 inch.

Yes, the CIBC carries CSA. That is the standard cited for it, so it is acceptable where a CSA marked fitting cover is required.

If the LB is a 1/2 inch or 1-1/4 inch rigid conduit body, the CIBC cover is the replacement plate. Take the old cover off and check the trade size stamped on the body, then order the matching CIBC. Reuse or replace the gasket separately if the location is damp or wet.

Material is the dividing line. The Thomas & Betts CIBC conduit body cover is stamped aluminum and carries CSA; the Crouse-Hinds 270 is a sheet steel Form 7 wedge nut cover. Aluminum covers are the usual pairing for aluminum conduit bodies, where mixing dissimilar metals in a damp or corrosive environment is a concern, while the steel 270 is tied to the Form 7 wedge nut body design. Pick the cover that matches both the body form and the body metal.
