Shallow Cut-in Box

[Trickyflea]

Does anyone know of a cut-in box for a 20A duplex receptacle that will fit in a hat channel furr out?
Hat channel is 7/8" tall and is mounted on concrete. General Contractor says that he has had electricians install recepts. in this fashion before.

PS I realize that my foreman's helper did not install the 4 square straight and plumb.

If it's 5/8" rock they make shallow handy boxes but I'm not sure if they have enough internal volume for the wire and a device.
