Tip: If the holes in the curved door arm and the straight door arm do not align, reverse the
straight door arm, select two holes (as far apart as possible) and attach using bolts (H15),
nuts (H20), and lock washers (H21).
If the straight door arm is
hanging down too far, you
may cut 6 inches (15 cm)
from the solid end.
