Window Channel Balance Help!

Thanks for posting. Before I can confirm what Series channel balance you have, I'll have to 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, please tell me what stamps are printed or inked on the surface of your channel.

Thanks for getting back to us! With a 1" deep show, I'd go with our Series 351 channel balance--for your difference sized balances, the S351-22 and S351-28, respectively. While yours looks slightly different, I think it should be fine. They serve the same function.

If your balances do not have any numbers stamped on them, I will have to know the weight of your sashes for both windows. You can determine this by removing the sashes from the window and placing them on a scale. Let me know!

Thanks for getting back to us. I'm sorry, but I think you may be confused. I do not need the weight of the balances, but rather the actual sash itself. This is the part of the window that moves up and down.

It's my pleasure! For both the 22 pound and 16 pound window, I'd select the 2140 option. This can carry a window sash weight of 15 through 23 pounds.

As for the 32 pound window, you should consider the 2760 option. This can carry 30 through 33 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.

Usually a stamp of 27 3 corresponds to our 2730 option, but you should weigh your sash and compare it to the weight ratings we show just to make sure that it's correct.
