Plastic
Plastic Knockout Bushings protect cable as it runs through the knockouts in metal studs. The bushings snap into place. These are plastic snap-in bushings for knockouts.

Rubber
Rubber knockouts insulate bushings for knockout openings and snap in to knockout openings on boxes in dropped ceilings or interior walls. This allows low voltage wires and cables to be run to devices inside boxes or enclosures. They have a smooth surface that protects wires from the sharp edges on boxes or enclosures.
