Pivot 15-167 & 21-C-30 counter balance

Thanks for posting! I can't really tell what your pivot shoe is based on these images. I'd have to see it fully removed from the window. I would also need to know its thickness and width. Just by eyeballing it though, I don't think it's the 15-167 as the top prongs are different.

The pivot shoes do lock when the sash is tipped out, however from there you can easily remove the sash and then pop the pivot shoes out. Take a look at our tutorial video for more information.

As for the balance, I think you might want to take a look at our S770-21 channel balance with the 21C option. The 21C option can support a window sash weight range of 14 through 18 pounds. Does your sash's weight fall within that range? Let me know!

Unfortunately, without having at least exact dimensions, I cannot suggest replacement with any reliability. Seeing it out of the window would also be a huge help. You could look through our Pivot Lock Shoe Section and see if there is something there you can use.

As for those balance weights, 21A can support a window sash weight range of 5 through 10 pounds, 21B can support 10 through 14 pounds, and as I said above, 21C can support 14 through 18 pounds.

Thank you! That makes things a lot clearer. I appreciate your patience with us. Now that I see it out of the window, and with detailed measurements, then I can say with more confidence that the 15-167 looks like a good match.
