Sliding window weather stripping

I'm afraid that we don't carry a type of weatherseal that matches these photos. It looks like yours installs using a flat base, though, which is how many of ours install as well. I'm reminded of our 58-135 bubble seal or practically any of our wool pile types.

The big question then becomes whether or not you can use these as a substitute for your old seal. I'm just not sure. It would depend on your dimensions. I recommend carefully measuring your sample and comparing it to the various wool pile types we carry to see if anything is the same size.
