I can only find double gang faceplace with 12 holes. I can install this on top of the elctrcal blue box for the top two screws.. However there is some space left after that since electrical receptacle is bigger. I can either put a blank face place or some other solution.
Ideally 3-Gang 7.1 Surround Sound Distribution Wall Plate w/ HDMI® size is perfect for the bigger electr receptacle but in I need square holes in there for connecting the keystones.
I havent seen 3 gang faceplate with square holes for keystones.
I assume by "blue receptacle" that you mean a blue 3 gang wall box. Something like this:
And the problem is that you want to use a 2 gang wallplate which will leave a portion of the hole into the box uncovered.
The right way to fix it is probably to cut out the existing three gang box and install an "old work" 2 gang box and patch the sheetrock as needed.
Better yet, if you specified a two gang box and the contractor installed a 3 gang box then get the contractor to come back and fix it or write a check for the cost of the repair to your satisfaction.
You may also be able to use something like these Decora keystone plates. (Be aware that sometimes one brand of keystone jack will not fit another brand of insert plate.)
If you go this route you would just need to get a standard three gang decora wall plate.
Hopefully this helps. If I've misunderstood the problem somehow please try and clarify and I'll try and help again. (or someone else will). If you familiarize yourself a bit more with the terms used to describe the items you are referring to that may help.
For instance... this is a receptacle: I've seen them in all kinds of colors, but I don't recall ever seeing a blue one. (although I don't doubt they exist somewhere.)
