What he posted is made for wire management in computer server racks. It works great for that application, and I would think it would work equally well under a stand. The lids aren't incredibly difficult to take on or off, although they can be fiddly with long runs of it. You can get it in various lengths and widths. Here is a link to some on Amazon, just so you can see what to search for. The width is measured in U, this is a server rack standard measurement unit. 1U = 1.75 inches. Don't ask me why we measure servers in U, it's just the way my life works LOL.
