39-139

A quick learner from New Mexico says:
Hello - I am looking for operators like 39-139 but need rear-mount. I saw a comment that suggested part #33-205 but I am unable to find that in your catalog. Am I just missing it, is it still available, am I looking for the right part number??? Thanks in advance for your help.

Thanks for writing in. So what we've recommended in the past is to use the 33-205 threaded nut to reverse install the installation screws on the 39-138 and 39-139. We've installed these with the help of a bench vise; you just press them into the holes at the front of the operator base. Let me know what you think.
