Double hung window replacement parts
Thanks for reaching out! Your pivot shoe looks like our 15-177. Look over the dimensions and compare it to your existing hardware to confirm that this is the right fit.
This shoe is compatible with our Series 152 coil balance spring. To determine the spring strength needed for your window, you'll need to look for any stamps on the metal coil.
If there are no stamps or they are hard to read, you'll need to get the exact weight of your window. Once you have the window weight, you'll divide it by the number of coils in the window to determine the spring strength needed for each side.
Your pivot bar appears to be part 26-226. Again, compare the dimensions to your original to confirm that this is the right replacement.
Let me know if you have any questions.
