4. Adjust the cabinet until the distance on each side is the same.
Then add ¹⁄₈" (3.2 mm) for the final measurement to be used
in the next step.
5. Use final measurement to measure in from each edge of the
filler board. Mark lines in such a way that the outside edges of
the filler board will contain the screw holes.
6. Place cardboard or other protective material on a sturdy, flat
surface. Position filler board on top of the protective material
to keep from cutting into the surface below.
7. Place a ruler or straight edge along the lines drawn previously
and use a utility knife to cut filler boards to size along the
lines. Make cut so the outside edges of filler boards will have
screw holes.
8. Pull cabinet part way out of window. Attach right filler board
to front of a side-mounting angle with two ¹⁄₂" hex-head
screws.
9. Place cabinet back into the window with right filler board tight
against window channel. Insert left filler board into window
channel.
10. Push left filler board against side-mounting angle and attach
with two ¹⁄₂" hex-head screws. From the outside, push filler
boards as far forward in window channels as possible.

board.
2. Cut foam blocks ¹⁄₄" (6.4 mm) wider and insert into channel
behind filler boards.
