Identifying Casement Operator

Thanks for posting. We can't say for sure what operator you need without seeing a picture of it in its entirety, including the link arm. If the appearance and dimensions match our 39-028, the 39-114L or 39-205 crank handles would work with this operator. If you are uncertain this is the right operator, please show us a picture of your entire operator from a bird's eye view, and please provide dimensions of the straight arm. For information on how to remove and replace these operators, see the video below. Many thanks.

Thanks for your reply. Reviewing all of your photos and information, I do agree with Bob in recommending the 39-028 operator. The handle you have now should fit the new operator as long as it has the same 11/32" diameter spline. Give it another look, along with the video Bob placed in his reply and let us know if any other questions come up. 

Got it. Take a look at our 39-114L crank handle, as well as, the fold down version, our 39-205. See if any one of these handles can work on your operator.
