This is a glazing bead for a vinyl double-pain window.

It's brittle from the sun and was falling apart as I was removing it to replace a broken glass. I need to purchase some, but can't figure out how to identify it by part number. I was unable to see any kind of brand name on the window fixture itself.

Based on the shape alone, I think our 55-164 is similar. However I'm not sure how our dimensions match up to yours. Look over our measurements and see what you think.
