Broken pivot bars (window brand unknown)

A landlord from Buffalo says:
Needing pivot bars for an unknown brand of vinyl replacement window. Somehow 4 of the bars broke on half. Attached are photos showing the broken pivot bar and with a tape measure next to it. I also included some photos of the sash bottom showing the screw hole and also a photo of the pivot shoe of these windows.

Thanks for writing in. See our 15-180 Pivot Shoe. This shoe is compatible with our Series 190 Coil Springs. For a new pivot bar, see if our 26-360 could work as a replacement.

Hi Bob,
Just the clarify...are you saying I would need to replace the complete balances (shoe and spring) and also the pivot bars? The shoes and springs are currently OK on this window, just the bars are broken.

If all you need to replace is the pivot bar and continue to use your other original hardware with it, that's fine. We are just providing the additional replacement pieces in case you should need to replace them at any time.
