channel balance replacement

A quick learner from US says:
Hello,



I am looking for channel balances for 2 different windows and would appreciate if you could help me determine the correct ones as well as pricing. I included some pictures and below is the information I was able to retrieve after removing them:



Window 1:

Brand: BSI

Stamping: 3530 EL

Size: 35" x 1/2" (metal part)



Window 2:

Brand: BSI

Stamping: 2930 EL

Size: 30" x 1/2" (metal part)



These windows are from the early 80s. I need 2 channels for each window.



I appreciate your help on this.

Hello,

We may be able to supply these balances for you but that top attachment is quite out of the ordinary. I'm going to have one of our senior experts take a look and we'll reach out to you as soon as more information is available. Thank you!

It appears that you have custom balances from Jones windows. Your first balance will have the 19-039 top fitting and the 15-002 bottom fitting with a 3530 spring strength. Likewise, your 30" balances will have the same fittings with a 2930 spring strength based on the stamp number you've provided.

One thing I'd like to confirm is that your balance with a 3530 stamp would normally have a 36" metal channel, similar to your 30" balance with a 2930 stamp. Once we confirm this information, we will send over a separate email with order links and price quotes for two of each balance. Thank you!

Hi Paul. You are correct. The length is 36" on the 3530.

Thank you.
