Replacing Window Sash Cords

Installation Instructions

Replacing Sash Cords
Older double hung windows use a pair of counter weights to hold the window sash open. The weights are attached to the window sash via a sash cord looped over a pulley. Overtime, the sash cords can deteriorate from sun, dirt, chaffing and layers of paint. Even if only one cord is broken, you should replace both cords while you have the window apart.
