I purchased this glazing several years ago to fit my Alco windows. It is different than the original, but works fine and I need more. It is 9/16" H x 7/16" W. I have been very pleased with repair parts purchased from you previously.

Good to see you again! Have a look at our 55-062-6 and see if this is a decent match.
