I originally bought these rollers as feed and eject rollers for trimming long pieces on my bandsaw. My table height is 1/2 inch below the stated max height of the reel stands - unfortunately they make it an inch below the max height. But honestly, it doesn't matter that they don't even reach the advertised height, because when you extend them all the way there will be no post in the base tube and they will tilt an inch or two, breaking the top plastic boot. After a few uses as a carpenter's roll for long work pieces, the plastic handle turned on a steel set screw and I now have to pry the beautiful handle off the screw and pry it out with a vise. Still, it's an effective stand to lean my push broom against, but so does my wall. Assembly was a challenge, as you have to put a second row of screws in a 2" pipe - to be honest, Grizzly mobile bases might be more difficult to assemble, but you don't feel like you wasted half an hour doing it have finished the process.
