I have a number of manual windows that are hard to open/close. The gears on the one pictured are completely "frozen"; we're hoping to buy one, and if it works, then proceed to order more (both left and right cranks). Please help to identify a suitable replacement.
Thank you,

Hey there!
Thank you for reaching out to us. This operator looks like it could be a match for the 39-253RB or 39-439B. The best match will depend on the guide used at the end of the operator's arm. I recommend watching the video below, it'll go over exactly what I mean.
If you need a new cover and handle, see the 39-452 (sold separately).
It is a little difficult to remove screws that are corroded or with stripped heads. I would suggest drilling out the screw heads and then possibly using a set of vise grip pliers to grab the screw and remove the rest of the screw. As for some type of anchor into the window sill, I would try using a little longer screw to go deeper into the sill. Take a look at the 33-016 screw or possibly a little longer.
