Hello, 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 operators. 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. Look them over and let us know what you think! |
