nope. think of a foot spotwelded to the box, that
you shoot to the floor.
16 ga. holds the box the right height off the floor.
doesn't need a stud to attach to. has a bent tab
at the top of the box, to keep it from flopping
back and forth in a 2 1/2" wall.
looking at it edgeways, it would look like this:

you shoot two pins thru the bottom track
to hold it down. a muppet scattering them,
and a guy with a hilti shooting them down,
can blow out a 10,000 sq. ft. floor in two
or three hours.
the guy scattering the boxes, as soon as he
was done, he'd grab a ladder and a stud
punch, and pop two holes thru the top plate
above each box.
the guy shooting down would follow behind
commander hole puncher, tossing pre cut and
stripped MC cable between boxes.
when commander hole puncher was done, he'd
start putting up switch boxes, and throwing whips
up from them.
as soon as you are out of the walls, you call for rough
wall inspection.
then both of them start throwing fixtures up in the
ceiling. when they are up, the muppet starts putting
jumpers between fixtures, and the journeyman starts
making up.
then comes the apprentice with the pole gun, blowing
ceiling wires in.
finally, you put home runs in, and make up the panel.
then everyone wires up fixtures and whips.
the precut whips and box stands save an awful lot of
time.
sasco was the first kid on the block to do this, and
were paying full union scale, and winning all the bids
against everyone....
edit... my little ascii drawing didn't survive the forum posting. sorry.
