I purchased the suggested channel balance and the delivered product matched the existing in length and end caps. However, the new balance does not allow the window to close. It stops about 2" short of the bottom of the window. Upon close examination, I observe that the spring of the new balance is mounted in a different hole. However, I am not certain that difference is the cause. What would stop the window from closing? I reinstalled the old channel balance and the window is able to close (although stiffly due to the corroded springs).
