I looked at that one too, and several others from Grainger. I think that one would work. But did you see the ratchet handle I linked to (bottom of my first post), would it be too weak? It is just like the one used on many strobe mounts. I like the ratchet handle idea because you can turn it any way you wish to get it out of the way, or, position for best leverage. With a heavy modifier, that shape of handle positioned to twelve o clock would give better leverage. If the one I linked to is too weak to handle that type of lever load, maybe there is a heavier duty version available.
The other thing I was thinking, why not put the wing nut (or a different type of removable nut) on the other side instead, then you could use the threaded bar with handle all the time, and just add the wing nut when you need to also trap the modifier. Maybe you could drill a hole in the threaded stock to allow the umbrella thumb screw to secure the threaded bar for the handle when the wing nut is not in use? Does that make any sense?
Season to taste, Dave ;) I tried a ratchet handle but decided it was too easy to overtighten:
Once the tension was properly adjusted with the ratchet handle, I found it necessary (or at least prudent) to also tighten the Einstein's umbrella shaft locking knob to prevent the threaded support rod from being pulled toward the rear of the light excessively by the ratchet handle. Incidentally, the umbrella locking knob does an excellent job of holding the threaded rod securely in place without the need for drilling a hole or dimple.
Fastening and adjusting the rod from the front of the light is possible but, as I mentioned in a previouse post, I do not find that convenient. Typically, the adjustment would not be performed until the modifier is mounted so access to the front rod end might be restricted or the rod end might not be in view.
