Help with pole extensions

A contractor from Colorado says:

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.

Thanks for reaching out to us. Unfortunately, we don't have an ETA on when out 39-157B will be back in stock at this time. Chains of supply have been backed up for about a year now, ever since quarantine started, and things haven't really settled down since. I can only promise you that we're trying to get these back on the shelves as quickly as we possibly can.

Concerning the 39-338 , we don't have a version with a ribbed spline on both sides. It wouldn't work that way. The reason it has a hex side is to use the 39-339 adapter, which allows you to install a handle on one end while connecting it to an operator on the other.

We do not sell extension poles, unfortunately.
