Andersen 100 Series Sash Balance Number 1650
- Works with Andersen 100 Series Single Hung Fibrex windows manufactured from 2008 to present.
- Every balancer has the number stamped on the edge - please see in image gallery.
- We highly recommend replacing both balancers even if only one is not operating properly.
- These balancers allow free and easy vertical movement of the lower active single hung sash.
- To visibly see the balancer you need to remove the lower active sash.
Note: Balancers have length and counter-balance information stamped on face. The first one or two digits identify the approximate length and the second two digits identify a weight range. One sash uses two balancers.
