This will restore the sash to a near new condition, and prolong the life of the window. Whenever replacing Window Channel Balances be sure to check the guides, take-out clips, sash cams and terminal clips , as age and weathering can make plastic and nylon parts brittle and worn. Even metal parts will show fatigue with constant use, so be sure to inspect them too. For Help on "How to Order Window Channel Balance" click this link .
