I want to install 2 NEMA 6-50Rs in a large 4 gang metal box Similar to below. I cant find a cover plate to take both receps. I thought I have seen flat plates before but I cant find them. Any sources, or ideas, or is this a waste of effort?

It used to be that P&S Sierra would do custom wall plates but Sierra has been gone for over 20 years, who if anyone still does it, have no clue.
 
Good feedback, thanks. At least I know its not a common off the shelf item. I didn't want to put effort into this only for someone to say "Why didn't you use this...."

Thanks.
 
So far, I can only suggest hole-sawing a 4-gang blank plate, or cutting and joining two 2-gang plates.

Kyle just responded to my email: "The custom plate would run well over $150.00+ and take 8 weeks."

They also mentioned a completely blank 4g plate for DIY:
 
I think I am just going to put them in 2 separate 4" square boxes and nipple them together. It will be surface mount below a panel. I did humor making one because I have access to a Tormach CNC mill.

I love MCMASTER for CAD files and sure enough they had a CAD file. So I was going whip up a CAM file in solidworks using HSM works for CAM and mill it, but then I thought what am I doing. It does not need to be so pretty, I just thought there was a neat solution besides the usual 4" square. I don't want to custom order one, just because that would be more of a hassle than making one. So 2 separate boxes it is, the usual.

another option which I have done before, is use a nema1 junction box with no knockouts then design a cover with the holes for your receptacles and have a laser cutting place make it. Heres a picture of one I did a few years ago to hold a bunch of deadfront GFIs
