2" Desk Grommet Black(10 Pack), Wire Cable Hole Cover Plastic Wire Organizers for Office PC Computer Desk Cord Management

Since these are made in China, it should be obvious that they use the metric system. These grommets are 50mm. After cutting a hole with a 50mm carbide hole saw, on a drill press, they fit perfectly tight and snug. They have small ridges for some extra holding power. They are made from hard non-flexible plastic, so they are easy to trim if needed.

Bought these to run cables from under a drum riser.A little super glue around the lip and it’s working great and makes for a clean look!MUUUUCH cheaper than Home Depot!

Nice product for chords other than regular plugs. A two or three pronged plug doesnt work with the little rubber piece.

Perfect and great price!

First of all I challenge you to find a better price at a retail office store. Not going to happen. These are literally 1/2 the cost for the same exact thing. So I'm really not going to complain about a very slight fitment issue. These run just a little under 2" in diameter. I'd say maybe 1/16 to small. With a couple dots of super glue on the sidewalls of the insert it's perfectly snug. I was going to glue them in any so no big deal. The cap fits tightly enough. As a part of my woodworking buisness I occasionally build custom desktops for customers. On this 10 pack I can easily triple of not quadruple my money back. I do recommend a decent brand holesaw so you don't rip the upper lip of the whole and leave chipout.

Worked out great, running cables to a work area. Look awesome!

Great for new desk. Gives it a finished look.
