Harvey double hung windows

Removed what I thought was the sash pivot screw and cannot remove the pivot.
The pivot shoe seems wider than the channel?
Appreciate any help in advance!! Mike



Hi there, Mike!
We appreciate you reaching out to us. I can't ID what balance you may have from these photos, unfortunately. Can you show me a photo of the attachment that your balance hook engages with? That should help steer us in the right direction.






Thank you for getting back to me! This is just what I needed. I recognize this balance and we can help supply replacements for it though it will have to be a custom order due to the configuration. What we'll use is the Series 770 but with the terminal clip swapped out for the 62-105 hook so that it connects with a pivot shoe like our 15-105 (sold separately).
I will just need a few more pieces of information so I can get this moving for you. Can you verify the length of the metal channel and the precise weight of the window sash? The Series 770 uses a different rating system so we will need to re-calibrate the appropriate spring strength.
I'm afraid you can't replace this balance with any other type of balance. We always recommend sticking with the original hardware that your window was designed to use.
As for the pivot bar, I can't be certain without seeing it removed but you can start by taking a look at the 26-416. Compare the specifications and see how they match up.
