I want to find a mounting arm that looks like this Sorry to use someone's photo in LG for this I do not know want kind of arm this is but I like it.

If you have access to conduit bending tools, you could make one yourself. Otherwise, electrical supply stores might have them.

@sol I do have access to conduit bending tools but the ones I tried to make came ether all wrong or simple 90 degree bends I wanted to look the pic. I try the supply house down the road from me.

You can go to Home Depot and find them in two different styles,long or short.
