Need help in identifying replacements for old block and tackle rod balances

Handy Person from Oregon
I have this style of balance and I need to replace them.
I can provide additional photos and measurements as needed.
I have 36" and 60" tall windows.

Hi there!

It looks like you have an older rod-type balance that isn't made anymore but our Series 775 channel balance uses the same shoe and can be used as a replacement. You'll just need to measure your bottom shoe and weigh your window sash to choose the appropriate spring strength option. There's a chart on the S775's product page that will show you which option you'll need based on the weight of your sash.

If you have any further questions just let us know.

This looks like what I need. How do I determine the length required?

Great! You will need to measure an undamaged version of your original balance. You want to measure from the very top of the black cap at one end to the very bottom of the white cap at the other end. Don't include the cord in your measurements in any way, and make sure that the balance is removed so that it's in a "neutral" position.
