Questions about this item

Does the Raco 2928RT coupling include the compression nuts and gland rings, or must they be purchased separately?

The coupling includes the clamp hardware needed for a compression joint; no extra nuts or rings are required for installation.

Should I choose the blue or the gray finish for a 2 in EMT run exposed to weather?

Both blue and gray are zinc-plated steel and rated rain tight, so either finish meets the same cULus 514B standard for wet locations.

What does the 2.78 in outside diameter mean when routing the coupling through a 3 in knockout?

At 2.78 in OD the fitting clears a standard 3 in knockout with enough room for the compression nuts to tighten without binding.
