Window Crank?

Quick Learner from Florida
We don't know what brand of windows we have? We installed Plantation blinds and now we need to find 4inch extension's to operate the casement windows. Can you help?

I'm not sure what to recommend based on just these pictures. Could you confirm the diameter of the handle's hole? Can you also show me the operator to which it connects?

The hole is 5/16. We tried a 5/16 RV window extension but it didn't fit?

If a 5/16" spline didn't work, then the hole is likely not 5/16". I would triple check your measurements just to be sure. There's a chance it could be 3/8", in which case our 39-422 may work for you. It's only 2" but you could stack two on top of each other.
