WE ARE LOOKING TO REPLACE 8 ANDERSON BAL ASSYS.
DO YOU HAVE A CHART THAT EXPLAINS THE NUMBER SYSTEM ANSERSEN USES.

I BELIEVE THAT THE MIDDLE NUMBER IS THE KEY

I NEED BL8/10#31/585 WHICH IS YOUR 24-1033 (33BEING THE MAX LENGTH)
D39/7#27/685 WHICH IS 24-737"
J15/5#23/385 WHICH IS YOUR 24-531.

HAVE I BEEN CORRECT.? I HAVE 22+ WINDOWS WHICH WILL AT COME POINT NEED THEM

THANK YOU

The middle number is key, and you are correct on all three balances. I have attached the balances to the right side of the page, just in case. Thanks for choosing SWISCO.com!

Unfortunately, the given information doesn't tell me which Andersen balance would be best for your application. The only way to accurately identify these is to reference the stamps printed on the balance box itself. There will be quite a few different stamps on there, but we're specifically looking for one with a "#" symbol in the middle of it. If no such symbol is on the box, it's usually safest to just show us every single stamp; we can eyeball the proper code.

Unfortunately, without that stamp it won't be possible for us to make a recommendation. We rely on that. That means you will need to return to the house and partially disassemble the frame to get a photo. If you aren't able to do that, then you may want to contact Andersen directly for assistance.
