This page is about the simple steps you need to take to install an aluminum window awning.
Flex Pan Window Awning Installation
The first step is to attach the top brackets. They belong at the top corners of the window and are held in place with 11/2" sheet metal screws. If the window has an aluminum frame that is exposed these clips can be installed right over the frame for extra strength. Small windows like this one require just two clips on top. Larger windows will require more clips to be installed.
Attach a stringer into each top bracket using the cotter pins provided. The brackets have multiple holes. I use the outside hole most of the time. You situation may require a different set of holes. Some awnings may have more stringers and support arms. If you are covering multiple windows space these between them. If it is one big window use the stringers without the support arms. Your awning may come with three stringers and two support arms, in this case the middle stringer just needs to be centered.
The return arms need to be assembled as shown before they are installed. Use the cotter pins provided with the window awning. The spacing between the holes is the same so it does not matter the end you attach the brackets to.
