I need to replace the spit arm operator in my Anderson casement window: it is has 0-9400A-1 stamped on the front, and F-9400-8A stamped on the underside. The window opens from right to left. Thanks in advance.

Those numbers correspond to a few different parts. Could you show me a picture of yours out of the window? That will help us find the best match.

Thanks for posting, I recommend taking a look at the 39-264. Also if your windows were made before 1999 then you will also need the 39-362 adapter plate.

Hello! This appears to be the same part as pictured above. Have you reviewed our recommend 39-264 yet? If not, I highly recommend that you do so. It looks like a great option.
