Help identifying parts and size

Question

Hello-

I need to replace channel balances on a bunch of windows in an older house. Most of the windows are completely missing channel balances. Is there a way to determine the length of the balance I need from the size of the sash?

I'm including photos from one of the channel balances I was able to remove. I believe all the others will be this same style. I can provide sash dimensions/weights for other windows if that is helpful.

BTW--the length of the metal portion of the channel balancer shown in the pictures is 26 1/16"Thanks,Steve

Thanks for writing in. This looks like a S385-26 or S380-26. The only difference between these two balances is the 'depth' of the bottom nylon shoe, so compare both with your old hardware to see what matches best. You will need a stamp option of 2530.

In regards to your other-sized windows; in general it is always most reliable to go by an old balance from the window, so we can't say for sure what you need otherwise. Similarly, we also cannot say for sure either if these other balances will still be either the Series 380 or Series 385. That said, if you can provide the following information for each window, we may be able to help narrow down the length and stamp options needed. Can you tell us the height of the visible glass in each window, as well as the exact weight of each window sash? From there, we'll try our best to recommend what you need.

One last point: if you know the manufacturer of the windows, that may help us confirm the probably Series you need. Many thanks.
