Thanks for posting. See either our 39-089 and 39-090, or our 39-187 and 39-188. The only difference between these two operator sets is the shape of the gear arm. You'll need to compare your old operator to both sets to see which matches best. If you're uncertain, we will need to see pictures of your entire operator, including the arm, from a top-down view. |
