Anderson, Narrowline,Double hung,1970. Window balance

We can certainly help you out. Can you please send us photos of your balance including both ends and any stamps or engravings on the metal? Is this for a tilt or non-tilt window? Finally I need the length and width of the metal channel not including the plastic ends.

Unfortunately, these cords cannot be replaced nor are they sold separately by any company. We also highly advise against even attempting to replace them, due to the amount of tension they're under. If yours have broken, you will need an all new balance.
