Window springs and pivot bars for Alliance replacement double hung window

Hi there!

Thank you for reaching out to us. Your pivot shoe is no longer available, but you can use the 15-177. This uses the Series 152 coil springs (sold separately). The video below will go over how to pick the correct spring weights.

As for the pivot bar, take a look at the specifications of the 26-449 and see if they match what you need.
