What type of crank is this?

Hey there!

Thanks for reaching out to us. We're happy to help with this. Details of the operator tend to be obscured when installed so we'll need more information. Can you remove the operator completely from the linkage and show us a photo of its link arm? We'd also like to see a clear shot of the top and bottom installation hole tabs. Those details will allow us to narrow down some options. 

Thank you kindly! Please allow us to look into this further. We'll reach out once we have more information. 

Take a look at the 3 awning operators we've related for you on this page. One of these should fit your window but I recommend you review the specifications for each and compare them with yours. The most important measurements are the bottom mounting hole center locations. My first choice would be the 39-074 used on Lenahan windows, but you should take a look at all the suggested operators along with the related hardware. 

Yes! You can find our return policy here just in case.
