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.

replaced this into my headboard that was intending to return after realizing the built in charging station provided was very limited but the seller offered to give partial refund instead of dismantling hassle so purchased and replaced just this and now double line my headboard with built in diy charging sation ⭐️⭐️⭐️⭐️⭐️
