Hi,
I would like to know if you carry this operator. It is a dual arm. Arms are 9 in. long. It has a screw in retainer plug with two flats. One side of the retainer plug that holds in the threaded shaft is about .622" while the other is about .685". The threaded shaft looks like the shaft/stem from a water faucet. It appears to be mounted with two screws into the frame on the outside. It appears to be made of zinc or pot metal. The root cause of the failure appears to be the insert plug outer thread failure so the stem/actuator cannot be held into turn the internal gear assembly.
Best Regards,
DaveĀ
