Hi,
I appreciate the all the details on your website. I cannot match up my window balances from windows bought at Home Depot in 2010 which and are American Standard Series 50 single hung vinyl windows.
Over the last year or so multiple balances on the larger windows have failed.
The metal potion only measures 23" and approx 9/16" wide (1/2"). They are stamped 22 11 but measure 23" (metal only).
The moving part of the window (sash) weight 38 Lbs.
I need to know which weight range balance to use, since there are two balances do I divide the window sash weight in half and therefore need 19 lbs. force for each balance?
Thank you,
Craig
