Window wool pile weatherstripping.

Looks like you need a type of wool pile, but I'm afraid I cannot make out your dimensions based on these photos. Wool pile dimensions get very specific, going into the 1/32" range, and your ruler is not sufficient. You'll also probably want to measure an undamaged version to get an accurate read. In the meantime, you can see our entire selection here. We have detailed dimensions that you can use as a reference.
