MyCableMart 4" Cut-Hole Size Black Round Wire Management Grommet with Removable Lid

This fit exactly what I needed, and the whole size was correct.

This is exactly what I needed. Thank you so much!

Good overall, but you'll need adhesive if it needs to be secure. The quality of the unit itself is fine, but it doesn't fit snugly into a 4" hole like it should. Yes I see that it says "3.993", but you would think it would be designed to fit a 4" hole made by a hole saw without a great deal of play - which it doesn't. 4" hole saws aren't perfect, nor is the hole that they produce. I'd prefer if they'd just make the thing 4" and shape the bottom accordingly, so it stays in the hole without the use of adhesives.

Was looking for a piece of trim to fit in a 4" hole in a can recycling bin. This fit perfectly! Good quality plastic too.

Just what I needed

Product was as described very easy to install I would recommend using it

Perfect fit!
