Channel Balance Question/Kolbe & Kolbe Double Hung

A handy person from 17601 says:

These are the older style with black clutch pre 2004 all upper sash on double hungs. Will the new balances need to be made smaller since the new balance are different clutch style and will I have to change to new style pivot ?

Hey there,

Thanks for reaching out! To determine the best possible replacement for your existing balances, I'll need to see a photo of your existing balances. Unfortunately, I am unable to identify them or confirm any information about the replacements without seeing a photo of them.

I'll need to see photos of the balances as well as any other compatible pieces of hardware. It would be best to see them removed from the window.

Please let me know if you have any questions.
