Looking for a cut-in box for MC cable and LV?

[Cow]

I'm wiring a shop right now with a conference room in it. I have two different locations I need a box for, they want to hang a projector on the ceiling as well as a flat screen on the wall. I'm looking for a 2-3 gang cut-in box that'll work with MC cable and have the ability to hold LV wiring as well. It would be nice to find a recessed box for the flatscreen, where the projector probably wouldn't matter if it was flush or recessed.

The best I've come up with is a Levition 690 which I'm not entirely sure will work with MC cable:

I see Arlington makes something similar, but all these recessed boxes are nonmetallic which makes me think they're geared specifically for NM cable. My supplier has no idea what to look for, so I've been through the Raco, Steel City, Carlon, Leviton catalogs already...

I guess I just don't know if plastic boxes are only rated for nonmetallic wire?

Thanks for the help.

In general you can't use nonmetalic boxes with metallic wiring methods. Check Arlington's metal A/V box line: http://www.aifittings.com/products/spec-sheets/tvbs505.pdf

THey sure have some nice products these days.
In the "old days" we would gang some Raco 518 boxes, add a set of "Hold-It" clips and a barrier... all of which were "stock items"..
The plate often took a few days to procure.

That was one of my first thoughts was to use gangable metal cut-ins, but I haven't seen any LV dividers, including one for those 518's you mentioned, so it seemed like a bust.

All the dividers I see are for boxes with mudrings or masonry boxes.

Lew Electric makes a floor box with a divider.
The only thing that makes it a floor box is the trim. The rest is a gangable cut in. Costs more, but it should work.

Tried to link to the exact image, but could not. Scroll down a bit to one of the two gangs and click on it to see what I am talking about.
