I thought of that (but did wonder about the Code compliance), but in
fact I think I'll just run Romex through the wall (between the studs)
for that section of the installation, come out through the sheetrock
into the back of a surface-mount Wiremold box, then continue with
individual conductors in Wiremold raceway from that point on.
