Cable Cord Grommet 3/4 Inch Flexible Wire Rubber Grommets for Desk and Other Furnitures Wire Hole Cover Cable Management Wire Organizer Cable Pass Through (8 Pack), Black Color

Go with 5/8" and all good.

Easy to use, flexible to put a usb through for my wyze camera.

I drilled 3/4” holes in the surface and inserted these grommets, and they hold my charging cables perfectly in place. No more slipping through the hole under the desk.

Too big, otherwise great

I wall mounted Sonos speakers and fed the power cord thru the wall into an attic power connection. These fit the 1/2 hole perfectly. I did not want big holes so I cut the plug off to feed the wire thru and then wired in a new plug.

Using these for a DIY project and they work great. Nice quality rubber grommets. What more is there to say? They work as intended to cleanly route cables.

Used these for cables coming up through the new luxury vinyl plank flooring I installed in our house. they look great.

I needed a 1/2" size for ethernet cable hole in corner of a room. All I found was this 3/4" size which I had to slit and trim to fit. I then secured in place with clear silicone. Looks good. But would have been better with the right size.
