Hello, Max. This pivot shoe is very similar to our 15-188 and 15-178. The only difference between them is the thickness, which was also the only dimension you gave us that was an estimate. You will need to get a more precise measurement to confirm which one of these pivot shoes is the right match for your window. If your spiral balances are still functioning normally then I see no reason why you can't keep using them. The only thing broken on your shoe is the center metal cam, which isn't indicative of failed balances. |
