Swivel box covers
 

I noticed Garvin has these swivel box covers.

These have a 1/2" or 3/4" female threading.

I assume you will need to make a male thread of an EMT pipe to connect to this? Or can you use a standard set screw connector without the "ring" and thread into this and connect a EMT on the other end - probably a single set screw is not a good idea?

What applications do these swivel covers have? For down lights in a garage?

It is not for conduit. It looks like a standard Bell housing hub for fixtures to me. Not weatherproof of course. I am not sure?

Edit. It is for conduit. LOL.

1/2" pipe is used in the fitting for downrods for ceiling fans.

Here is a link.

It says:

Solid, one piece 4" square box swivel hangers for 1/2" pipes are used to hang light fixtures, security cameras, speakers and other electrical/electronic devices from standard 4” square junction boxes. They require no extra mounting boxes and hangers, and allow a 20° swing from vertical. They are great for industrial settings where conduits are bumped or jostled occasionally.

this is for use with threaded rigid conduit (GRC), not EMT.

:laughing: Does the precessing improve air movement?

I just have this vision of a ceiling fan swinging around the room in a giant arc.

I guess if the ceiling is sloped it helps in getting a vertical downrod?

But the descriptions says "They are great for industrial settings where conduits are bumped or jostled occasionally."

That makes me wonder, does it hang loosely? When you bump into a pipe stemming from it, does it move and then swing back to the original position?

Or can you "tilt" the rod and angle it, like you would the arm of a desk lamp and it will stay in that position?

The ones I have seen are exactly like a ceiling fan mount. They work well in dropping outlets down to a work area or for hanging lights on a downrod over a work area. The will work with ceiling fans as well, but a balanced fan is important. And they will swing when bumped, they do not lock in place.:yes:

They are commonly used for commercial high bay lighting. Or used to be anyway.
