Noisy replacement channel balances

Thanks for posting. You may not have the right channel balance Series installed in your window. You see, stamp numbers are not identification numbers; they are merely indicative of the balance's strength. They do not correspond to any of our existing Series, directly.

The best way for us to ot help you identify the correct replacement hardware for your window is for you to take a few pictures of your original balances for us to look at.

If you do, please make sure you take a picture of the attachments on both ends of your balance, as well as the stamp number. The attachments will help us identify your Series.

Also, be sure to include the length of the metal channel itself. Do not include the plastic attachments in your measurements.

Thank you! These do appear to be similar, but I can note one major difference right off the bat. Please examine the two bottom shoes and compare them to our 15-004 and 15-005 channel balance shoes. The dimensions you're matching here is the depth. As you can see, the two shoes I've mentioned are 1-3/32" deep and 1" deep, respectively. Which one more closely matches your original bottom attachment?

Just to play it safe, I'd also like to know the weight of your window sash. While your balance is marked 26 4, which corresponds to your 2640, I think it's best that we investigate the weight of your sash just in case.
