Lincoln casement window operator?

Thanks for posting! I'm sorry to say that we would not be able to supply you with a suitable replacement for this operator. If you can confirm with certainty that Lincoln is the manufacturer of your hardware, you may be able to reach out to them for guidance on where to find a replacement. Although, I cannot make any guarantees.

Our sincerest apologies that we cannot be of help with your repairs but please feel free to reach out with any other hardware repair questions you might have.
