Window cranks

This appears to be an awning window operator. We sell quite a few different models, which you can see here, but I can't narrow it down based on the provided photo alone.

Before I can make a suggestion, would it be possible to see yours removed from the window entirely/ I need a clear shot of the link arm without obstruction. I'd also like a head-on shot that shows me all the installation holes at once. Please let me know if that's possible.

In the meantime you can navigate our selection to see if you can find a good match.
