Casement crank old MW?

Hello,

If you could open the window and show us the operator arms that move the sash in and out, we should be able to determine what replacement options are available. Thank you!

Thank you. This looks like an older version of our 39-013 and 39-014 operators. Take a look and see how the 13-1/2" long-arm compares to yours. If you notice any discrepancies, let us know and we can go from there. 

To remove these types of operators, you'll most likely need to remove the wood framing converting the installation screws. Though the operator is different, the video below does a good job of demonstrating this process.
