I am looking for a replacement snap-in glazing for 1990s era ALENCO windows. The profile is a simple quarter-round cross section in white but I cannot match the dimensions. I scanned your site but could not find anything that was a good dimensional match. Any help you could provide in identifying a replacement would be appreciated. My best cut at dimensions for the molding is 0.31 (5/16) inch for the straight edge that sits against the glass, and 0.44 (7/16) inch across the opening.
Many thanks in advance for your assistance.
