I'm looking to purchase the white pile weatherstripping for a sliding glass door repair and I believe the one I found should work, but I would like to know the thickness of the bottom "track" or "fin" so I would know if it will fit in the corresponding slots on the plastic weatherstripping. The item I'm looking at is 58-126, and I'm fairly conifident that the width and height will be fine. But the description says nothing about the thickness of the plastic bottom that slips into the track. It appears as though the track I have is about 1/32" thick. Any idea how thick it is on item 58-126? Thanks
