I have 3 identical windows like this from Window World, sized 46" X 52"? Each window has these two seals on the bottom and is leaking air. I was able to remove one, but on the other one, the 'hairs' keep pulling off and preventing me from sliding it out of the track it is in. The one I got out is 39-7/8 long and the other one is the same length. I need enough of both gaskets to reseal all 3 windows.

Hello. Compare to the 58-183, 58-182 or 58-171 Foam Seals. See if one of these matches what you need.

It appears to be 55-183 based on the dimensions and it has a hole on the middle of the foam piece. What about the felt-looking strip in the 3rd picture? The one I cannot even get out of the window?

Thanks for your patience. It is difficult to say what the wool pile might be without knowing the exact size of the base, and the height of that pile. Wool pile dimensions are very specific, often going into the X/32" range. If you can carefully get a sample out with needle-nose pliers, that would go a long way. In the time being see our selection of wool pile here.
