I have some Traco sliding windows and need some felt weatherstripping. The plastic base is 1/4 inches and the pile is 7/16. Hope this is enough info for you.

Thanks for posting. Based on your dimensions, you could consider our 58-105 or 58-126. Their measurements are not exact, but they're the closest I've been able to find. See what you think.
