casement window operator
Hello,
We'd be happy to look into this for you, but we have no way of confirming the operator your window uses without seeing the original. Is there another similar window in the house with an intact operator you could show us, including the arms that move the sash? If so, that would help us narrow down your options. Thank you!
In that case, unfortunately, we have no way to narrow down your replacement options, but you're welcome to look through our selection of casement operators here.
Casey is correct that, since there is nothing to measure and the style of the operator is an important factor, we won't be able to determine what you need without seeing the original hardware. If there are any labels on the window, you could try reaching out to the manufacturer directly to see if they have a record on the parts used on your window series.
