Thomas & Betts CIBC-2 2 BLANK ALUM COVER

It's a blank cover, so there is no opening in it. Use it to close off a 2 inch conduit body where you only need a splice or pull point kept accessible, not a device or fitting mounted through the cover.

The CIBC-2 is the 2 inch size in the Thomas & Betts blank aluminum cover line, so it pairs with 2 inch trade size conduit bodies (LB, LL, LR, T and similar) of matching make. Covers are sized to the body, not to the raceway run, so match the body's trade size stamped on the casting.

The CIBC-2 is a blank stamped aluminum conduit body cover. The Arlington 933 is part of the AnyBODY series and is supplied as an LB conduit body cover with a gasket sized for 1-1/4 inch. So the two differ in material and in what comes in the package: the CIBC-2 is the bare aluminum blank plate, while the 933 pairs its cover with a gasket. If you need a gasket for a weather-exposed LB at 1-1/4 inch, the 933 covers that; if you are replacing a blank aluminum cover plate, the CIBC-2 is the direct fit.

They serve the same purpose but are built differently. The Crouse-Hinds 270 is a Form 7 wedge nut cover made of sheet steel, so it uses a wedge nut fastening arrangement and matches Form 7 conduit body geometry. The Thomas & Betts CIBC-2 is a blank stamped aluminum cover. Match the cover to the body form and fastening style already on the fitting rather than treating them as drop-in swaps, and consider the material if you are keeping an all-aluminum run free of dissimilar metals.

Stamped aluminum. That keeps it corrosion resistant for exterior and damp-location runs where a steel cover would need coating, and it stays light for overhead work. Aluminum should not be used in direct contact with concrete or in areas with heavy lime or alkaline exposure, where that attacks the metal.

The CIBC-2 is sold as the blank aluminum cover itself. If you need a gasketed assembly for a wet or damp location, the Arlington Industries 933 AnyBODY LB cover ships as a cover and gasket set, though it is the 1-1/4 inch size rather than 2 inch.

Stamped aluminum covers like the CIBC-2 use the conduit body's own screw holes and are the straightforward replacement for a lost or damaged cover on a standard body. A wedge nut style, such as the Crouse-Hinds 270 Form 7 sheet steel cover, mounts with the wedge nut hardware specific to that form and suits Form 7 bodies. Match the style the body is prepped for; the two are not interchangeable.

Choose a cover that ships with its gasket. The Arlington 933 AnyBODY cover is supplied with a gasket for a 1-1/4 inch LB conduit body. The Thomas & Betts CIBC-2 is a blank stamped aluminum cover, so if you use it outdoors you will be sourcing the gasket separately to suit the body. For a single 1-1/4 inch LB where you want cover and gasket together, the 933 is the simpler pick.

It can. The Thomas & Betts CIBC-2 is stamped aluminum, while the Crouse-Hinds 270 Form 7 wedge nut cover is sheet steel. Facilities that want to avoid mixing metals on aluminum conduit bodies, or that are concerned about corrosion in damp areas, generally keep the cover material consistent with the body. If your existing bodies are Form 7 with wedge nut fastening, the 270 matches that system; for aluminum blank cover replacements, the CIBC-2 keeps the assembly in one material.

CIBC-2 is the manufacturer part number. It's a single configuration, so there are no finish or material options to specify when ordering.
