Can round #window #screen spline fit where flat spline is used

I want to replace my patio screening, and the old spline is flat.

I have a hard time installing flat spline.

Can I use round instead? .190



Depends what shape the spline groove is. Some of the old screen doors from the 1950's used a wide flat screen groove and there is no way you could make a round spline fit in one of those.

But if the screen spline groove is square and only .190 - .200 inches wide there should be no problems.

Some of the old doors use .250 or 1/4" square aluminum as a spline and those can be replaced with .250 or .270 round spline.
