Window glazing bead

I bought my house 2 years ago, it's a relatively new construction (98) but I have no idea who the windows were made by. There are no names or numbers on anything I can find but they are all plastic (vinyl?). Attached is a picture I took of a glazing piece I removed and another I found online that looks identical. The dimensions are .720" along the end with the lip and .675" along the other. I'm guessing 3/4 x 5/8. Looking to replace a few broken glazing beads as well as have replacements for some windows that need leaky panes replaced.
Thanks
