Replacement Casement Operator

A handy person from Palatine, IL says:
I'm looking for replacements for my casement operators. The part # on the bottom is C-1040-9A. The outer arm has a sliding clip. The outer are attaches to the under side of the window. There is a triangular logo on the mechanism. It might be the letter "A" w/ a double underline. Distance between the outer most holes is 3 13/16".

Thanks

Good morning! Thanks for posting, and for the great pictures. I'm not very familiar with this operator, actually. Would you happen to know the name of the manufacturer?

In the meantime, please take a look at our 39-317 Split-Arm Operator. While it's not an exact match, it may act as a possible substitute in this case. Compare it to your own hardware and let me know what you think.

I'm shocked to find someone with the same info!

I'm looking for a casement operator with the same markings on the bottom (C-1040-9A). The image I've attached shows the measurements on mine.

I did not put down the measurements between the "ears" of the operator assembly because I believe that is the measurement the original poster was talking about when he said "Distance between the outermost holes is 3 13/16" - I say this because that's the same distance between those "ears" and the holes in them (the two "ears" outside the blue lines in my picture)

Any new info on something like this, or a better alternative to fill in? The house we bought is completely missing the LEFT-hand window operator, and I've had no luck finding anything to replace it.

Thanks for posting! Unfortunately, we haven't been able to find anything exactly like this quite yet, but since this thread was started we have added a few other operators to our catalog that may also work as substitutes, along with our 39-317. For instance, you could also consider our 39-171 or even something like our 39-315. However, these are just suggestions, and we can't say for sure how well they will work for you. What do you think?

Thanks! I think I'll give the 39-171 / 172 a try and see how it works.
