Looking to replace window handle that can fold

Hello,

I see that the photos of your older hardware have a centered handle, which the holding handle in your last photo has a handle that mounts on the right side. If you could open the windows and show us the arms that move the sashes of both operators, we'd be happy to confirm which parts would be compatible for both assemblies. Thank you!

Your operators with a centered spline would use the 39-107FK handle and cover kit. Take a look and let us know if you need anything else. Thank you.
