This is the end piece for the spring in the side channel of my window. The spring itself is not in a tube like most I have seen. The spring is 20 inches long and looks like an old screen door spring. The spring and the top connecting are fine. I just need this small plastic part. I cannot find a name or part number anywhere on the window .

This looks like an older version of our 15-104 friction shoe. I think this may be what you want but check it out and see what you think.
