Dual arm operator

Question

The sprocket (crank?) is worn and cover has no collar for sprocket to stay in

When that worm gear breaks, it means the entire operator has to be replaced. I think this might be either our 39-031 or 39-155, depending on the length of the link arm. Compare both with your old operator to see if either matches up. For a new cover and handle, see our 39-107 and 39-114L.
