Folding window make 5/16

Hello,

We would need to see a photo of the operator that this handle attaches to, as well as the arms that move the window sash in and out, to confirm the correct replacement operator. In the meantime, take a look and compare our 39-205 folding handle with an 11/32" spline size to yours. 

The only male handle that we carry would be the Roto 39-226 with a 5-16" hex shown below. Take a look and see how the specifications compare to yours.
