Thanks for posting! This is a very unusual operator. I'm wondering if this is for what is known as a French Window, where you only need one operator to open both windows. Either way, do you think you can adapt our 39-021 Wood Window Crank to work with this setup?

Thank you. That makes things a lot clearer! You have an old-style awning operator. You may have to use a newer style like our 39-015 Roto Gear Window Crank, or maybe our 39-083 or 39-140 dual arm cranks. You would have to look at their dimensions and determine what would fit best. Keep in mind that you may also have to install new hardware to accommodate the new operators.
A quick learner from Atlanta says:
We have several older casement windows, which cannot be easily opened/closed because the teeth in the crank mechanism (4" wide square) have worn down. I found some markings on the crank: DET 4.235.01 (detroit)? There is a ~8" arm that extends to the track (~29" long). The arm is straight for 7", then bends and joins the crank mechanism. As far as I can tell, the entire assembly to fastened together, so I might need to remove the flashing and wood to remove the entire thing as it is screwed into the case below the sill.

The first picture shows the crank mechanism and the second shows the connection between the crank arm and the track.

Thanks for any help!

Thank you for posting. I've placed you into an existing discussion regarding this very same operator. Check out our posts above to see a couple ideas of what you can do.
