I need some help with your operator crank extenders.
For starters, I see that your 39-157B is not in stock. Are you going to get more? When?
Next, on your 39-338 is see one of the holes has a hex socket. Which end is that? Do you have one with a ribbed spline on both ends? Do you have a converter?
Finally, what about an extension pole for this? I see you have a ring for the pole, but I don't see a pole for this setup.
