crank for window

Hello,

I can't be sure with the operator still installed, but the 39-430 would be a good place to start. Take a look and compare the specifications below to yours. We also offer the 39-429 opposite-handed version and 39-232 handle used with both assemblies. Just let us know if you notice any discrepancies, and we'll be happy to confirm if a closer match is available. Thank you!
