Andersen Screen Spline

Good afternoon. I would like to order some spline for my Anderson window screens. They are 3' x 6' Anderson Double Hung Standard windows built in Oct. 1983. The screen bar total width is 1" approx. but not counting the spline slot they are 3/4" wide. The spline now in them and it may not be original from Anderson is hollow rubber 7/32" (.2188)approx. and has 13-14 cogs.. I am not sure if the rubber would be best or the foam 59-250 or 59-270. Would you please advise me so I can place an order. I will be rescreening 12 windows.

Hi, we have Anderson Screens from the mid 1980's. The most common is #2852. They currently have what appears to be old ridgid vinyl splines that curled up when I removed them. Do you have replacement spline that will be easier to work with? There are nine that need replacing they are approximately 63" long and range from 26 to 32 inches wide.

Thanks in advance!
