crank handles

Looks like you have two different kinds of operators here, but they both use the same handle. If you want the folding variety then I recommend the 39-205. 

Please note that if your intent is to install shades that don't overlap with the operator handles, then you won't find any handle that will give you the necessary clearance. In almost all cases it is necessary to install the shades out from the wall so that you have full clearance. In other words, the shades have to make way for the operator, not the other way around.

I agree that the 39-107FK can replace the hardware you have pictured. I see nothing that would prevent it from working since it accepts the same 11-32" spline as the 39-205.
