Searching for ANDERSON CASEPARTS

Hello, thank you for posting,

Are you looking to replace the full operator or just the crank handle? I have related the Andersen operator handles we carry on the page for your review. These handles fit on to a 3/8" gear bore. 

If you need assistance with a replacement operator. We will need to see pictures of the window open where we can view a bird's eye view of the operator base and arm attachment(s). Thank you!
