What ~bushing~ do I need for a KO

[mobiledynamics]

I plan to make 2 holes via KO on the cover of a pull box.
I want to add a rubber/etc *bushing/gasket* on the hole I make so it's not a sharp hole.

Any ideas what this ~whatch-ma-callit~ is called.

Snap in bushing.

What are you feeding though it?

 

[mobiledynamics]

It's a big 16x16 pull box with multiple conduits going into it - located behind a rack. Low voltage stuff

 

[zmaxmotorsports]

If its just low voltage and its protected Id just use romex clamps.

 

[mobiledynamics]

Negative on the clamps. It's got to look ~clean~

Plastic strain relief:

I'm making the KO on the cover of the pull box. Just something to line the ID of the hole - to keep the appearance nice and neat....even though the hole should be clean and burrr free
