I need 231' of bulb weatherstripping to replace aging weatherstrips on my Windsor made windows. I prefer the foam filled ones that tend to keep their shape better.

Your style of bulb weatherstripping, 58-053, doesn't come foam-filled. We don't find that the hollow bulb has any issues performing well, but it's your choice.

Thank you. I thought the foam filled ones may maintain its shape better over the years.
