What is the protuberance seen in the image on the mast/shaft a foot or two above the stand?

The umbrella comes in two pieces and that is the area where the two pieces meet. One part of the pipe fits into the other.

It is over a foot, but closer to one foot than it is to two feet. I'm afraid I can't be more specific than that since I no longer own it. I hope that can help, though!

You adjust the height and "spread" of the base by loosening the friction handle and re-tightening. Then the main mast has pins and holes approximately every 8" to hold the height you want.

I would say it is slightly higher than others, 2-3" or so. I can't say that I've seen one higher, but haven't specifically looked for that.

The angle of the stand is adjustable - there are two angles; a lower one and a taller one - both are landscape.

The flexible part of the mast (between the fixed ends) is eleven and a half inches. In a natural position, with the light facing down, the distance from desk to top of the lamp is about twelve inches.

The stand has only one position. Uncertain on the bit question and am off work due to illness. I woukd have to check. Sorry.

It's a mic stand. It's got a standard 5/8 threaded mounting configuration like all mic stands. The shaft is adjustable upwards from the image of the item. If your issue is the stability of the item, the base weighs about 2 pounds, and seems quite stable, especially at the lowest height setting. It would take quite of bit of weight and a lot of leverage to tip this over IMO.

The third device does not have an arm, but attaches to the main mast, so no real movement. There are quad stands you may want to consider.

Approximately 3 1/2". I know that they show a couple of inches below the 1" deck of my pontoon boat.

The pipe section is about 2 feet tall and the base most likely would tilt in the wind

In upright position the stand projects out perhaps 6-9 inches in the vertical plan from where it is when it is in the lowered position.

The stand is metal and plenty strong for the globe. I love mine, especially the blue ocean areas -- very attractive globe for the home and reference. Oh, and the globe does turn sideways and up and down. You'll love it.

I am sorry, but I have no idea, but what I can tell you is that is a damn good TV stand. I've had one of these for a couple of years and still looks good.

I found a spec sheet online somewhere before I bought mine. It might have been on the MonMount website for item # 194B but I don't recall. Anyway, if I understand you correctly, I laid a ruler on the base behind the shaft and measured to the edge, it was difficult to read because the metal curves but it looks to be about 33 mm. Keep in mind that the mounting plate is not completely flat, there are 2 large bolts that hold the 2 halves of the base together so the bold heads add a few mm to the width. I'm not sure if I can upload pictures here but I will if I can.

The legs are about an inch tall ... but the underneath clearance is only about 1/2 inch (here and there) due to the design of the micro-wave.

visual estimate from the one I have mounted: greater than 5 feet, most likely less than 6 feet.
