I don't think the measurements for the holes match up. My unit has only two installation holes (one on each side) and they appear to be about 4.25 inches from center to center.
Thank you for your quick reply. The 4-1/8"between the attachment holes is correct. The arm on my broken unit, however, is 9.5" long rather than 9". I'm thinking this still might work. Would you agree?
It's too bad about the color, but I can live with it!
Thank you. I have ordered the part.
Hi Jasmine!
I received the new crank and the screw holes are the correct distance apart, but there are some problems. The screws are smaller in diameter than the original ones, so they do not grip the frame of the window. I have one of the old screws, and it does not quite fit into the new crank unit. I am attaching photos. The rusty screw is the original screw, and the shiny one came with the Swisco replaceent unit.
A secondary issue seems to be a design flaw in the unit. This may not be fatal but it's annoying. The curve of the crank holder is so close to the hole that the screw cannot be screwed in all the way. Images 7969 and 7979 show this: 7969 shows where the paint rubbed off when I tried to screw it in, and 7970 shows the screw fully inserted into the hole.
I'm primarily looking for an answer to my first question. Do you have a thought about how to firmly attach this unit to my casement?
Thank you, Suzanne

Thanks, Dave. This is helpful. I did find a screw that does the trick, and when I have a little more time I till try what you suggest to make it a bit more weather tight.
