Our 39-107 and 39-102 look like they could work, but it seems the gear bore of the operator has come out. If that has happened, then the gears of your operator have been stripped and the whole thing needs to be replaced.
Please open your casement window as far as it can go and show me a few pictures of the operator arms fully extended. That will give us a better idea of what can work as a replacement. |
