    "Telespar" is one trade name for the sleeve tubing used, but there are numerous sources for the leg materials

    Nice idea. Most likely the company that made the metal for the legs was MSMetals out of Michigan. They make the bulk of the sign post material in the United States. It will be difficult to adjust the height but in most cases, you make it for a certain height and rarely change it anyway. I would make three changes though. First, use bolts that just go thru the nuts. Second, turn the bolts around such that the head of the bolt is on the outside of each table. Finally, move the legs under the table about 3 inches from each corner. This will help to keep from bumping it with your legs. Again, nice use of materials.

    The main brand of these telescoping perforated tubes is Telespar, made by Unistrut.

    They make two fasteners for the Telespar product that could be beneficial to applications like this.

    One is called the "Corner Bolt". It is a specially designed bolt that goes through one of the holes and comes out through a hole in the adjascent side (not the opposite side). You can put a nut on it and fasten it with a single wrench since the bolt cannot turn. When tightened, it clamps the two tubes to each other very rigidly.

    They also make a product called "Lock Pins". These pins slide into holes on opposite sides of the tube, and then swing down (by gravity) to a position that prevents the pin from slipping out. It is very fast and very secure, though it does not clamp the two tubes together.
    Best picture I could find is here, along with the corner bolts...

    This page also shows a variety of brackets and fittings to assemble these tubes into racks and stands and signs and what-not.
