To determine which sash balance is required for your window, either remove the balance and locate the balance number or click on the "Download Balance Size PDF" below.
Note: When using the Balance Sizing Chart, first determine your model number from the Unit Size Chart. Then choose the balancer from Replacement Balance Size Chart. This balancer will work for either the upper or lower sash. The Clear IG Balancer is for windows with standard Low-E glass (Most common type glass). The Tempered Balancer is for windows with tempered glass (Also known as safety glass that will shatter into small pieces when broken).
