Works great
Color: Black, Size: 6FT
Perfect for my application. I installed mine in my metal garage cabinets to allow me a place to store equipment battery chargers out of sight.

3 inches plus!
Color: Black, Size: 6FT
It works well BUT you will need a little more than a three inch opening. I ordered this as a replacement for a plain plastic grommet. I had to buy an attachment for my drill to make the hole a tad bigger and smooth out any bumps in the hole.
