Pivot lock shoe




Thanks for posting! Your coil balance shoe appears to be an older discontinued shoe that is no longer made any more however, our 15-177 is now the recommended solution. Look over the dimensions and compare them to your existing shoe to determine if these might be the right fit. These function a bit differently than your old assembly, because the spring screws to the shoe instead of hooking onto it, but it should still work fine as a replacement.

This pivot shoe is compatible with the Series 152 coil springs. To figure out the spring strength you need for your sash, you'll check the old spring for a stamped number that you can match.
If there are no stamps, or you are not able to cross-reference them, you'll need to obtain the exact weight of the window and divide it by the total number of coils in the window.
I've also linked a few other pieces of compatible pieces of hardware. Let me know if you have any questions.
