The Balance spring is from an Alcon window. It has a part number 2910. The metal channel is 1/2 inch wide by 30 inches long. Overall length with end pieces is 31 inches. Looks like you photo of S380 or S385. I need 6 of them for 3 widows with the end pieces installed.

See our S380-30 or S385-30. The only difference between these two balances is the bottom nylon shoe depth, as shown in the picture below. The Series 380 has a shoe that is 1" deep; the Series 385, meanwhile, has a shoe that is 1-3/32" deep. Compare both with your old hardware to see what matches best. If your balance's shoe is in fact less than 1", let me know.

In any case, you'll need a stamp option of 2910.

Thanks for your help. My bottom piece is less than 1 inch wide. Mine seems to be only 7/8 inch wide.

We do carry a bottom attachment with a 7/8" depth, our 15-029. I would recommend checking another balance as well since these attachments can wear down a bit over time. If you're confident that you need the smaller 7/8" attachment, we can have them custom made for you since we do not carry a stock balance with this attachment.

It looks like I really need the 7/8 inch. I checked 2 windows out of the 3 windows and they have the 7/8 inch bottom pieces. I have 2 questions. What is the cost of the proper custom version? Could I just purchase the standard series 380 and use my belt sander to remove 1/8 inch of material?

Custom balances would be $11.80 each. Let us know if you'd like to go the custom route and we can get an order link together for you.

That being said, you could use the S380-30 balances and shave down the bottom attachment a bit. Just keep in mind that once the balances are altered, they can't be returned for a refund.
