I wanted side window awnings to allow me to open the windows
in the rain. The nicest design that I've seen is Jason's
( kirkman), so I unapologetically stole it.
I found some extruded aluminum at the scrap yard in a C section, which I painted and attached with 3M VHB tape and sealed to the surface with butyl putty. Also from the scrap yard, 1" aluminum pole, 1/2" aluminum tubing.
The fabric is Sunbrella from eBay. The rubber tips are from a local big box store. I used polyester outdoor rated thread to sew it and a soldering gun with cutting tip to cut it. The turned ends are from a hobby store.
I made an aluminum bracket to attach the nylon tensioning strap and VHB taped it to the side. The nylon strap locks with a cam lock fitting to hold it tight.
The entire thing comes apart and rolls up in a case that I made from the excess material.
Due to the curvature of the UHaul
I had to mount the C channel centered over the window, though to block rain, it is desirable to overlap the opening part of the window more. I am able to slide the whole awning
back about 6" due to the wooden stick that secures the fabric in the C channel mounting (as shown in one picture).
