Got tired of lifting the screen door slightly every time when opening it do to the lower corner catching the bottom door frame.
Purchased a cheap, lite-weight turnbuckle from Home Depot and installed it at the campground. http://www.homedepot.com/h_d1/N-5yc1...1&ddkey=Search
The screws that came with the turnbuckle kit were to long, but I had some shorter screws in my TT junk drawer. Oh, the reflection in the screen door is from my tinted plexi-panels.
