Art Lites,
Did you notice that the handrail brackets ALSO hold the translucent window strips in place? Do not forget to put window strips in place first. (Do not use silicon ) Go slow, study your Greenberg Manual and you should not encounter problems. If you run into any buggers there are those on the forum willing to help.
Timothy Sprague, YOU BETCHA! I'm quite sure that Art will be grateful for your recommending the long reach pliers.
