13-D-40 14 window balance

Quick Learner
I recently sent in a question regarding balance stamp numbers trying to match one up to mine. I found the wifes camera and now have a picture of my "unique 13-D-40" 14" window balance. Do you have a match? Can you email me the product number and I can then place my order. Thanks, Tony

Thanks for posting, Tony! I'm afraid that I cannot identify your part number based on this stamp. Stamps are usually indicative of the balance strength, not its Series. To know the Series, I'd have to know what plastic attachments are installed on either end of the metal channel.

I see you have posted under the S770-14 channel balance. Do you believe this is what you have? If not, can you please show me some pictures of the attachments on either end of the balance?

Thanks Tom. As for my balance, I'm not sure what it is, I'm just guessing. I do plan on replacing both balances in this window as the spring is broke and not useable. There is no plastic attachment on the other end,see new photo, just two rods for the spring to hook to. The spring measures 6 3/4 inches from hook to hook. There is a small number located just under the series stamp which reads "30/96" It is hard to read, could be 95. Thanks for your help, Tony

Thanks for getting back to us, Tony. I think I know what your balance is. It will have to be custom made, however. I'll go ahead and email you a purchase link and price quote for your review. You can use this to place an order on our website.
