Just purchased a left and right of the S140-9. We took out the old spring balances and installed the new S140-9, but the window doesn't want to close all the way. About a 1/4 inch from being able to lock the window. If I can master this window, I want to buy these parts for my other windows. Is there a video on how to install them?
One more question on the S140-9 quick tilt single. What is the length of the coil? Could it be the coil is not long enough? My window in about 30 inches tall.
Thanks,
Robert
