Hello, Your exact pivot shoe has been discontinued and is no longer available but the good news is that our 15-177 Pivot Shoe will work well as a replacement. Look over the dimensions below to confirm that this is the right replacement for your existing coil balance shoe. 
Alternate image for 15-177
These shoes are compatible with the 1/2" thick Series 152 coil balance springs. To determine the correct spring strength for a particular sash, you'll need to locate the stamps on the original coils. If there are no stamps or markings, you'll need to use the exact weight of your sash divided by the number of coils used on both sides of the window to choose the correct strength options. The S152 coils are used with the 15-143 bushing, 15-144 cap, and 15-145 support barrel. As for your broken pivot bars, I would recommend removing an undamaged version from one of your windows to compare to the dimensions of the options we've related on this page. If none of them is an exact match, please get back to us with another photo of an intact part with your exact dimensions written out. Thank you. |
