Simonton windows channal balances

Thanks for posting. Before I can confirm what Series channel balance you have, I'll have to know a bit more information.

First, let's figure out what your bottom shoe is. Please look at the measurements for our 15-001 and 15-002 bottom shoes and note their depths. As you can see, they are 1-1/8" deep and 1" deep, respectively. Which measurement more closely resembles your own shoe?

Please also tell me the length of the metal channel. Do not include the plastic attachments in this measurement.

Finally, I'd like you to confirm the weight of your window sash since your stamp, "29 9," does not correspond to any of our available options. The "38#" makes me think that your sash might be 38 pounds, but I would like you to confirm, just in case. You can determine your sash weight by removing the sash from the window and placing it on a scale.

Thanks for getting back to us! Our balances come with the attachments already installed.

With the 15-001 and 19-002 attachments, it appears that you have our Series 390 channel balance. Please see our S390-30.

For the stamp option, I'd choose our 2940 option. This can carry a sash weight range of 23 through 28 pounds.

Please keep in mind that the weight range 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.

If the weight of your sash is approximately 24 pounds, then I wouldn't worry about that #38. It is likely just a manufacturing mark at the end of the stamp.

If a balance has too high a rating, then then window would be very hard to open. Like I said, though, the 2940 stamp is perfect for a window sash of 24 pounds.
