Drake...we have made mounting brackets to make box vertical before but our
customers complained about aesthetics.....Hence the search for a parallel
to the roof slope mounting box quest......Bob O i will look at the midnite
dual pole 600VDC option....That sounds like what we are looking for....
Thanks....
