I purchase the wrong bubble seal for my windows,# 58-055 2 bags, and I am not sure which one I need. I purchased them last winter with the intention to repair them this summer. The bubble looks like 1/2" at the flat side, the slide lock is 3/16".I hope this is enough information. Thanks Harold Jenkins

Thank you for posting. From your photos and dimensions, I recommend taking a look at our our 58-164. It looks like this may work for your vinyl sash.
