24-637 Andersen Sash Balance, 623, 627, 631, 637

Hi, I'm having trouble identifying the current part number for an Anderson Narroline window balance. The visible glass on the lower sash measures 28 1/2" high x 24" wide. There are two sets of numbers on the broken balance: 11600-17 and 062 7227 6-86. Thanks! Casey

how the heck is the plastic piece across top of 11600-17 supposed to come out? we managed to get one out and see that there is a metal box on each side of top-- sash balance box, i guess. and how is that sash balance box supposed to come out? thanks!

need a pair of sash balances for a 3032 Anderson window. C37 6#23 11-77 also for a Anderson window 3046. I don't know the numbers on this balance as I have not pulled it.

11600-3 and 11600-17 Also C23 6/23 1985 no other numbers other than patent number which is 335455 & 1967 CAN lower sash unobstructed glass is 24" 1/2 wide 20" height. can't figure which replacement (737 maybe?) or 531? Thanks Paul

I need replacement Balances the ones I took out have a number stamped on them its C43 6#23 9 87 can you tell me the Replacement Balance for this ? Thank You

Hi, I hope you can help me without having to go back to the jobsite. I'm working on a double hung Andersen built "about" 1987. The balance has several numbers on it: H17 623 6-8, 11600A-3. Without a magnifying glass the ID on the pane had C1G-2 4-00. However the last two digits may have been "88" ... (cont.)
