Spiral Bakance parts

Quick Learner from Fairfield Ohio
Hi

I need 20 balances. I believe I need the series 300 ones. Mine are 21 inches long, 3/8 inches wide, red tip. My windows are non tilt single hung aluminum windows from the mid 70s. Windows are in good shape but none of them will stay up. My question is I don't see two of the parts I found. Below the plastic shoe or boot at the bottom was a small metal piece hanging off the end. Not all balances had them on there and I'm not sure where they go. The other piece is the metal piece that was attached to the side of the window frame that the shoe or boot went into. Not sure if that piece has been replaced by something newer. Any help would be appreciated before I order.

Thanks

Dave

Hello, Dave, thank you for posting. Your window has been out of production for at least 35 years. From your photo, it does look like our S300-21, but with the smaller 15-020 shoe (see dimensions to confirm). Also see if your bottom sash clips look like our 17-014 and 17-015. If not, please send a photo of your bottom sash clips so we can identify them.

Regarding your balance fork, they been out of our inventory for around 15 of those 35 years and no one is manufacturing them anymore. The fork makes it easier to install, but to be honest you can just install the balances to the sash. After we confirm what parts you have, I will give you more detailed instructions.
