Channel Balance 2590

Thanks for posting. I don't believe you have either our Series 350 or our Series 351 channel balances, since your attachments both have wings. It more closely matches our Series 380 or Series 385 balances.

Keep in mind that the stamp marked on your balance is not a serial code, or any kind of identification number. It is merely indicative of your balance's weight capacity. Unfortunately, your stamp of 2590 does not match any stamp options we can put on our balances. We will have to know the weight of your sash to proceed.

As for what Series you have, I just need to know a bit more information about the bottom attachment. Please take a look at our 15-004 and 15-005 channel balance shoes, and note their depths. As you can see, they are 1-3/32" deep and 1" deep, respectively. Which one more closely matches your own bottom attachment?

Yes, the 2540 option can support a window sash weight range of 19 through 25 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.
