Nuair window channel balance

A handy person from Ft Myers says:
Good afternoon, I need to buy two new channel balances for my nuair windows and it appears they may be out of business. I would like to order some from you company but my codes on the balance do not match yours listed. Please help. The code on my balance is 86U 34-9 EB5 CMC 1. The overall length of metal is 35". Looking at your balance top and bottoms and after measuring it looks like I have 19-002 top and possibly a 15-005 shoe. I will post some pics to help you make a better decision. Please advise.

Hi Jeff,
Thanks for sending the detailed photos. Looks like SWISCO Balance Series 380.
Please remove the window sash and place it on a scale.
We need the weight of the window sash in pounds to determine the proper stamp option.

Thanks for posting! Please take a look at our S385-30 channel balance, which appears to be a very close match to your hardware. Also be sure to select the 2920 stamp option.
