Hello,
I'm looking for a replacement casement operator for one whose internal gears are stripped. It was installed in 2018 (unfortunately the quality on these operators has been poor; the ones in other parts of the house aren't doing well either). I didn't see a serial number on the operator, but on the arms, it says s-1081-60. The window panes are Anderson. To see more of the operator I'd need to take apart the trim. BTW the window is 17 inches wide, and the shorter arm of the mechanism is 4 inches.
Thanks for any help! Ben
