I used this grommet for the entertainment center wall behind my TV and it looks good and works great. Came with all the tools I needed to cut the hole in the wall and install it.

I bought these to provide a snug fit for an EV charging cable running through my garage wall. They worked perfectly to keep out drafts and crawly things. Highly recommended.

Worth the money!
Size: 50mm/2inch, Color: Black, Number of Items: 2
This kit is great. I bought this because I know that the seller paired the cutting tool to be the perfect size and it was! Not just that, but the hole cutter was well done and cut thru the 3 layers - laminate, plywood and particle board with ease. The only thing that I would do different, is go to 3" next time. 2" was very tight when running the 2 @ 120 volt cord ends through the cap.

Very sturdy under desk mount
Color: Black, Size: Width up to 13.4''
I'm using this with an Asus Prime micro-ATX case on a sit/stand desk, and it works beautifully. It's expandable, so it would have no trouble with a full ATX case. The PC is well supported and there is no wobble whatsoever even when the desk is moving between sitting and standing positions. Highly recommended.
