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.

Fits and works just as expected
Size: 50mm/2inch, Color: Black, Number of Items: 4
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.

Nice Floating Shelves
Color: Oak, Size: 24" W x 7" D x 1.5" H (2 pieces), Color: Oak, Size: 24" W x 7" D x 1.5" H (2 pieces)
I wasn't sure how to fill this space between my kitchen cabinets, and I think these shelves turned out looking great and fit the space nicely. They were easy to install, good quality, and could handle a decent amount of weight.
