The Awning will NOT stay in adjusted angle position.  I loosened both nuts on each side, adjusted to the desired angle then tightened backup TIGHT.  No matter how tight the awning will not stay in place.  NOW, I put 6 holes in the siding over my sliding glass patio door for what seems to be a decorative 12 foot long rolled up awning.  I'm kicking myself in the you know what because I can't use it for what I need (shade over my outdoor dining table).  SAD.
