Certainteed window insulation strips that fit into a 1/4 inch channel

Question

I would like to replace some of mine that have been worn down. Do you sell this?

We might have weatherstripping that works for you, but I have no idea what you might have. We'd need you to remove a small sample of the old one and show us a clear picture of its end profile, like the example drawing below.

We'd also need you to confirm its exact size. Many types of weatherstripping are close to 1/4", but are usually more in the sixteenth or even thirty-secondths range. It's important to be as precise as possible. In the meantime, you can see our entire selection here.
