I don't believe we have an exact match for your window frame. Take a look at our 59-050, though. It is a vinyl sweep like yours. The leg that goes into the window groove looks like it could be the same as yours, but the sweep itself on the 59-050 looks wider than your sample in photo. We also have a wool pile type that might work. See our 58-185, though I'm not sure if it will keep the water out as well as a vinyl sweep would.
