I’m trying to find a certain kind of bracket to mount a cage fan like this on my porch.

The fan is currently bolted into an overhead 2x4, but I’d like to be able to move the fan to several locations around my deck easily.

I’d like to use brackets similar to those used to hang most ceiling fans except more compact obviously. They are like a “U” or “C” shape and a disk or ball slides in and drops down in the bracket. This would be ideal so I can easily pick it up move the fan to a different bracket.

The photo below is the closest I’ve found, but still not quite it. These don’t have a drop or latch of any kind that would keep the fan from falling out if it’s mounted to and overhead beam.

Can anyone find this bracket. I know they exist… But Ive googled for hours and don’t know the right term to find them.

I found the ones in the photo by searching “keyhole bracket” .

Any other quick connect bracket recommendations are also excepted.

Thanks!
