The clear space above any windows or doors and an overhang or obstruction above is 8 1/4"s. We suggest a minimum installation height of 7' 6"s to provide headroom at the front bar when fully extended.
Approximately 1" per foot of extension. With a 10 foot extension the front bar will be about 1 foot lower than the mounted height. The pitch is adjustable from about 1" per foot to 2"s per foot.
We do not recomend installer but any general handyman should be able to install the awning easily. All Bst Awnings are designed for easy homeowner installation.
