Window crank replacement

A quick learner from Durham, NC says:
Patent number2732726. I need a few right hand and left hand cranks that will replace these. Several of them have stripped aluminum gears inside the crank.

Thank you for reaching out to us. I'm afraid we don't sell an exact match for this. According to our records, the old Miami operator isn't made anymore but you might be able to use the 39-054 though we can't make any promises. Look over the specifications and see what you think.

Keep in mind that the installation holes may not be exact and the slot in the window frame may need to be filed to allow space for the arm. 

Dimensions for 39-054
