Product Code: 39-375

A quick learner from Lee's Summit, MO says:
Can you tell me if your folding crank handle Product Code: 39-375 would be a direct replacement for the crank handle above. Looking to replace our cranks with nesting cranks so the handles dont walk off. Our current handles don't have a set screw they just snap/pull on and off.

Also curious how you remove the old? I don't see any screws holding it on but it won't move. the windows are certainteed casements from 2009.

Thanks!

It's tough to tell from this picture, but I believe this operator might be something like the 39-253RLB or 39-438B . In theory then, yes, the 39-375 would work for this. Just make sure your cover can in fact be removed. If it can't, you'd need to either use a handle that folds like the 39-205 (but it won't have a nesting cover to fold into), or consider replacing your old operator with one of the ones I mentioned above. In that case, you could use either the 39-375 or 39-451 , depending on the style you prefer. 

To know which operator you have, see the video below.
