I have 20 year old Andersen windows and sliding doors.
I did the Windows using your 59-250. At the time there was questions regarding .025 vs .027 splines. Your website said .027, but many users said .025. Your tech support line said .025 and I used that to perfection. Now I am ready to screen the Andersen sliding screen doors. Is the same .025 recommendation good for the doors. I will be ordering 48" standard fiberglass screen material from you.Thank you!
