Splendid build quality. Very solid support for a Dremel 4000 anyway, and that can be fixed with the knurled screws or screw on the bracket (screws included). Three tubes to a height of 37, 71 or 110cm. To use only two tubes, simply insert first the central tube. Goes up and down cables for the power cable and down to the hose. And locations for some tools. I am very satisfied with my purchase.
