Double Hung Wood window Balances

Question

I have two different sizes of windows, double hungs made initially by Weather Shield. Wood sash with vinyl channels and steel balances. Mine are stamped 3230 and 3240. Exclusive of the plastic end pieces, they are 33 inches long. I need two more of each balance, and I'm confused why the same windows appear to have both 3240 and 3230 balances. Are the uppers different from the lowers? Please let me know what you have in stock and if your balances come fitted already with the two end pieces. Thank you.

Hello,

The stamp numbers that you provided indicate the strength required for your balances to support the weight of the window sash. For this reason, the upper and lower balances could have different stamps if one sash is heavier than the other. I'm sure we have the balances that you need, but we'll need to see a picture of one removed from the window to point you in the right direction. All of our balances come fitted with the necessary attachments and ready for installation. Thank you!
