Two types of Pivot Shoe
Hello! This old pivot shoe isn't made anymore, but I have had a lot of success using our 15-046 as an alternative. The design may be different but it interacts with both the pivot bar and balance in the same way. The only thing you need to do is ensure that the dimensions are the same: specifically width" x thickness." They should be, but you can never be too safe.
As for removal, jamb liners will work for you but these can be expensive and I don't normally advise buying a set unless you plan on repairing many, many different windows for a living. It may be easier in your case to just make the cutout yourself. The video below will show you exactly how we do it.
