and washer through one of the boom mounting holes in the top
plate, then the boom, and finally the bottom plate. We recom-
mend starting with the 3-mm anchor hole first. Once the screw
is all the way through the sandwiched set of plates, push
another flat black washer on the other side of it before finally
placing a 3-mm locking nut on the bottom. Repeat this for the
second hole on the boom (see Figures 2-12 and 2-13). Once you
have one boom installed, repeat this entire step for the rest of
the booms.
