I'm afraid that we don't have a flat spline that is exactly 3/8" wide. Our 55-109 is a rigid flat spline for storm door screens that is 13/32" wide. We also have a flexible sliding screen door spline, our, 59-241, which is 11/32" wide. I am not sure if either could work for you, but they are our closest matches. Look over the dimensions and see what you think.
