I don't know if this will help, but I had screens custom made for a trailer at a store called, Brinson's in Plains, MT. They had the aluminum for the frame in two colors, white or metal. I gave them the dimensions and they cut and fitted them and then put the screen fabric in. It was very inexpensive. I had five
windows done and the materials plus labor was only $130.00. The only down side was they did not carry the springs to hold it in place. You can purchase those at Lowe's and if you get it to Brinson's, they will put it into the screen for you. Hope that will help you. :O)
