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.

Quality Product

Easy to install and comes pre-wired. This works as advertised and is easy to add to a new furniture build or retrofit into existing furniture.

Great for price
Color: Black, Size: 6FT
Worked great in the predrilled spaces in retail environment on counters. Had to do minor shaving of the existing holes but worked great after that. Only took 3 mins to correct. Well hidden and flush with counter.
