Need help choosing correct Andersen window balancers

Question

Hi,

I have a number of Andersen windows in my circa 1986 home with broken balancers.

The windows all have upper and lower sashes, but are of different sizes.

I exposed the balancers, sanded them with some very fine sandpaper to bring out the rediculously faint stamp, took photos, and sharpened them in photoshop (see attached).

The first window has sashes that are roughly 32"W x 23.5"H, and the balancer marking seems to read, "D63 7#27 8-86". The # could also be a small 4.

The second window has sashes that are roughly 36"W x 27.5"H and the balancer
marking seems to read, "E45 9#27 8-86".

Finally, the third window has sashes that are roughly 24"W x 19.5"H, and the
balancer marking seems to read, "B1 4#19 8-86".

Based on what I've been able to find on these old part numbers, I believe I need:

24-737

24-939

24-431

Can you please look at the attached pics and confirm my conclusions?

Thanks!

Dan

Thanks for contacting us! These pictures are a huge help. I believe you are right on all counts. Based on each of your stamps (specifically those with the "#" symbol), I think the three Andersen balances you picked out are the correct matches!
