I would like to replace pile weatherstripping in Champion windows that are 25 years old. Windows are in good shape but weatherstripping is shot. As you'll note in the photo sent, there is no way to insert the plastic strip into the slot because they are blocked by side frames that are not removeable.
Is there an altenative to installing? The strip base is 1/8", not certain of the pile- maybe 5/32.
Thank you
