upgrading the crank to windown blind friendly

Hello,

We'd be happy to look into this for you but we would like to see a photo of your operator with the window open so that the arms that move the sash are fully visible to confirm if our folding Andersen handle would work for your repair. Thank you. 

Thanks for getting back to us. Your operator resembles our 39-264 shown below, which uses the 39-152 cover and 39-301 folding handle. Take a look and compare the specifications of each part to your original hardware. 

Dimensions for 39-264

Yes, it will as long as the specifications of your original operator match the 39-264 that we showed you.
