Hi,
My screen has what might be an odd ball size of Black Flat Spline width is .2625" by .081" thick about 17/64" by a little more then 5/64" I believe there has been some shrinkage. Would you happen to have the different sizes of Black Flat Spline?

Thank you

95 % of the Lanai's and screen porches in Florida seem to use flat spline .09375 x .34375 or 3/32" x 11/32"

Some of them use a slightly curved spline that is almost the same size. .09375 x .3125 or 3/32" x 5/16"

Your spline is almost 3/32" thick and you are probably right it has shrunk. But the width of 1/4" is a little too small to have shrunk down from 11/32".

Your spline must be something special that was made specifically for the company that made your screen porch.

The only thing I can suggest is finding a local door and window repair store that may have glazing vinyl normally used for trimming out around the perimeter of glass.

Sometimes I have been able to use glazing vinyl that close enough in size to work in replacing a unique spline size.
