I have 2 casement windows in my kitchen where recently the cranks have came off and we are unable to open or close the windows. I am not sure on hopw to idently the correct replacement parts that are needed. Also, are there any options that you offer to assist in installing these parts other then the how to guides?

The top image is the right casement crank that is broken. The measurements for this crank base is 4 inches wide and 1 3/4 inches deep

The bottom image is the full right casement window that the crank operates. The measurements for the actual screen is 55 inches high and 11 1/4 inches wide. The actual right frame is 58 1/2 inches high and 13 3/4 inches wide.

I hope this information will assist in pointing me in the right direction on what the proper parts needed are.

Thank you

Tom

It is hard to tell what you need with the operator still in the window. It is possibly the 39-014 or the 39-028 but I really need to see a picture of operator out of the window to be certain.

Are these operators hard to take out? If i am able to do this myself, i will take a picture and attach that to this thread.

With the operator broken it may not be easy to get the window open. First, remove the screen insert. Next, unlock the window. Then try pressing on the window sash and see if it pops open, press on the frame of the sash not the glass. I would only do this if you can get to the window from the outside of the house so you can close the sash back up and lock it when done. If you can get the sash open you will be able to see the arm of the operator and possibly identify it or take another image for us to research. This type of operator is mounted to the sill of the window frame with screws and the arm connects to the sash by riding in a track, you can normally find a detach slot in the center of the track.
