Crank out window hardware
Thanks for reaching out! I believe this may be the link arm for an older style operator. However, I'll need to see the body of the operating mechanism to confirm.
Are you able to provide a photo of the entire crank operator?
Thanks for the photos. As I suspected, the part you are searching for is a link arm for an older model ROTO operator. We can offer a replacement for the operator base and the handle, however, we do not carry the link arm you have pictured here. That part has been discontinued by ROTO, and we have not been able to source a suitable replacement for it.
I do apologize for any inconvenience this may cause.
Please let me know if there is anything else I might be able to assist with.
I'm happy to help. And, again, our sincerest apologies that we cannot supply you with a replacement.
Feel free to reach out with any other hardware repair projects you may have.
Have a great day!
