Identify balance for replacement

Question

Dear Swisco,

I need your help identifying which window balances to order. The only identifying number marked on the existing ones is "14 4 JR CALDWELL." The existing is a 1/2" x 15" metal channel with plastic ends (clips?). The bottom (clip) appears to have a depth of 1-1/16". The window total is a 33-1/2" x 33- 1/2" vinyl single hung.Unfortunately, I cannot provide the weight of the moveable bottom sash, because the good balance is all that is holding it in, and I am hesitant to remove the window until I have replacement balances. If possible can you cross reference with your numbers. Thank you, for your time and attention to my inquiry.

Sincerely,

Mark

Hello, Mark. Based on the given information, I recommend the S385-15 channel balance with a 1440 stamp option. I am fairly confident that this will work for you. The bottom fitting on this balance is 1-3/32", which is a little thicker than yours, but I would wager yours was the same and just wore down over time.
