Window crank gear part
Hello,
This is the worm gear from a casement or awning window operator. Since this part is not meant to be removed or replaced, unfortunately, you'll need to replace the entire operator assembly. To determine what you need, we would need to see your operator with the window open so that the arms that move the sash are fully visible to compare to our inventory. Thank you!
Thanks for getting back to us. Unfortunately, we do not carry an exact match for the assembly shown in your photos. Our 39-379 is similar but it is for a skylight window, while you have an awning window, so we can't be sure if you would be able to adapt our operator to work for your application. Take a look at the specifications below and the related items to see what you think.
