404.8(B) barrier pic

[Twoskinsoneman]

(277v lighting). I have a situation where I am removing occupancy sensors and replacing them with 3 way switches at the two entrances to a large room. Each half of the room has its own circuit and now they want switches at the doors. Even though I know about 404.8(B) , I have to confess I've never actually seen a switch box with barriers. It appears contactors are the common solution but if I could get a metal 2 gang switch box with a barrier that would make me the happiest.
Anyone have a pic of one installed?
Thanks.

Here's the type I used although if plastic was readily available it was my choice.
A number of manufacturers make them Raco, T&B, Hubbel, etc...
The one shown is actually designed to be installed before the mud ring was put on the box but with a little fanagiling they can be put in later and is another reason I like plastic.
