Thank you for posting. Before I can recommend a balance, I will need a little more info.

First, I would ask that you please measure just the metal channel portion of each of your balances. Also, if at all possible, take a profile picture of the bottom attachment. I'm still a little unclear as to what it might be.

If it would help, please take a look at this chart and refer to your bottom attachment. Let us know if it matches one of these options; if not, please tell us, and we can work from there.

Thanks for your timely reponse.

The length of both balances is 30".

15-005 is the attachment.

Attached are additional pictures of the balances

and sash guide.

The sash guide resembles the Norandex 18-161

The top is our 19-005 Winged Channel balance Top, and you picked the 15-005 Winged Channel balance Shoe, so it will be S380-30. Your top sash guide is, indeed, a 18-161 Noradnex Top Sash Gide.

However, we will need the weight of your sash to get you the proper spring, because the 2990 option is a custom balance.

To weigh your sash, please remove it and place it on a scale.

Thanks for your reply,

The window with the markings 29.9 GW, CMC 11
weighs 29 LBS.

The other 29.9 DW,CMC 10
weighs 30 LBS.

Your 15-005 measures 1", mine measures 15/16".
Does this matter?

Hello,
I do not believe the 1/16" difference in the shoe depth will cause a problem, if it is too tight you could sand or file the shoes down a little.

Choose stamp option 2950.
30" Series 380 with stamp option 2950 will carry a window sash weight range of 28 through and including 32 pounds.

This information is based on 2 balances per sash. Balances are designed assuming friction in the jamb weather-strip will carry a portion of the sash weight. Suggested sash weights are approximate.
