Casement operator handle

It looks like you need a handle that fits around a hex gear. Is the gear 5/16"? If so, see our 39-230 or 39-224. 

Unfortunately these handles only come in a white finish. You may be able to spray-paint them if you have the resources to do so. I apologize for any inconvenience. 

Hello again. Unfortunately, the folding base comes attached with these handles, and we cannot sell them separately. I apologize, as I know it would make things a bit easier. That said, there might be slight differences in design with older versions of these handles compared to the new replacements, so it's possible the folding base wouldn't fit the body of the newer handles, thus making all-new handles the safer option anyway. In any event, sorry again for the inconvenience. 

I am afraid this likely means the operator itself has worn down and should be replaced. Please send a picture of the entire mechanism, including the link arm(s) that push and pull the window closed, and I'll see what we can find for you. 

Bob's not here today but I can assist you from here.

This screw only tells us what Bob has already surmised; the gears in your operator are stripped and you need to replace the whole thing. Once that worm gear comes out, it can't be repaired or replaced in any way. You need a new operator.

We can suggest a replacement, but we have to see the whole thing out of the window. Not the worm gear here, but the whole operator.
