I think your best bet to replace this operator is our 39-027E and 39-028E. I don't know if anything else we carry will replace this old operator. It's better to go with a shorter arm (9-1/2" in this case) than longer, since the worst that can happen in the case of a shorter arm is that your window won't open up an extra couple inches. Worst case scenario with a longer arm is that the window won't close an extra couple inches, which is of course no good at all.
You may also need a new handle and track. See our 39-114L handle and 39-533 track. |
