Thanks for posting. Assuming the nylon ends are identical on all of your balances, start by looking at our Series 390 channel balance. This may work for you. This comes with a 19-002 top and 15-001 bottom, so as long as these match your nylon ends you should be okay. We offer a variety of lengths and spring strengths.

THe 19-002 top seems a perfect match, but 15-001 bottom does not have wings. Mine has wings and looks match to 15-004, so should I look for series 350 instead?

I need to find out Sash weight. Can I find them by reading the print label on my own balance? How do I read these print label?
1/2" x 27", 26 5 HX CMC 11
1/2" x 23", 22 3 GX CMC 7
1/2" x 23", 22-5 IX CMC 11
1/2" x 18", 17-2 JX CMC 11
1/2" x 23", 22-4 IX CMC 11
1/2" x 18", 17 2 GX CMC 11
1/2" x 27", 26 5 HX CMC 11

Quick response would be very appreciate and I would like to make order as soon as I find out those information. Thank you so much.

Yes, I would recommend looking at our S350 channel balances.

In regards to figuring out your sash weight, 26 5 typically translates to the 2650 option at checkout.

-22 5- 2250

-17 2- 1720

Hi Tom , I seen your post and thought I could ask you a question regarding the the window balance bars. I am looking for 26 4 gx cmc 7, these numbers and letters are on the old ones, how do I know which ones to order? Your help is greatly appreciated.

Hello! The stamp doesn't really tell us much about the Series, unfortunately. All it tells us is how strong the spring is and how long the metal channel is; in your case, 27".

The only way to identify the Series is to match up the top and bottom nylon fittings. I recommend watching the video below for clarification, then seeing our entire selection of 1/2" channel balances for non-tilt windows. You should be able to match up a pair from that point.
