Window casement operator
Thanks for reaching out! There is a chance we may be able to replace this operator but I'll need to see a photo of the entire operator to confirm the exact replacement. Please provide clear photos of the operator arm(s) and how the operator connects to the bottom of the swinging window sash.
You may need to detach the operator from the window to get a clear photo.
Please don't hesitate to reach out with any other questions you might have in the meantime.
Thanks for the additional photos. This operator can likely be replaced with the 39-379 Skylight Operator. To confirm that this is the right replacement, you'll need to carefully look over the dimensions below and compare them.
The compatible handle is the 39-114L Crank Handle.
