No. 2008 NEC section 314.20 says "In walls and ceilings constructed

Okay. Thank you. I'll do it right, even if it requires borrowing a
ladder for the second half. I drive a LeBaron convertible, that
only takes a class 1 hitch, or whatever is the least strong. I got it
mostly to hold a bicycle rack, and I bought a one that has a square
upright-holder that screws on to the draw bar. Then with angle iron I
made a fork shaped upright with only 2 tines about 18 inches apart,
and I used a big piece of foam rubber on top of the windshield, and I
can borrow the ladder now without making my friend deliver it. At
least when the weather is good enough to put the top down. I start
off trying to make a canoe rack, and ended up with a much less
impressive ladder and pipe rack. I had no place to keep a canoe,

I bought the hitch for the first Lebaron, but I've used it on all 3
for a total of 20 years so far. I could use it on other cars too if
the struts holding the rear bumper are the same distance apart, or if
I can somehow drill another hole in the horizontal hitch bar, which is
3/8" or 1/2" thick and looks very hard.
