Screen corners for campers, caravans and mobiles

I find myself doing lots of repairs other people are unwilling to do. There are more mobile homes manufactured homes and people living in large campers around me then stick built homes. If you've ever worked on an RV or mobile home the very first thing you find is that most of the stuff that needs routine maintenance is not a standard size. Everything in them is smaller, thinner, shorter. You cant just go to a hardware store for things. You need a specialty shop. If they have what you need in stock it will be double the price of the standard size version. Anyway I was asked to replace some window screens and immediately found dry rotted corners. These corners are not in stock anywhere I can find and the only option without new corners is whole new screens. Not an option considering the price. I tried to scale other corners but they wouldn't fit so I made these. They will fit the skinny undersized aluminum rails found in mobiles, RV's, etc. they are a tight fit and will most likely need to be tapped into place.
