Metallics KOB100 – Frequently Asked Questions
1) What size knockout does the Metallics KOB100 bushing fit?
The KOB100 is the 1 inch size, so it goes into a 1 inch trade-size knockout or opening in a panel, box, or enclosure. Order the matching trade size to the knockout you are lining, not to the wire you are pulling.
2) What is a plastic knockout bushing like the Metallics KOB100 actually used for?
It snaps into an unused or oversized knockout to give conductors a smooth, insulated edge to pass over instead of bare sheet metal. Electricians use them on panel and enclosure openings where wires enter without a connector, to keep the sheared edge of the knockout from cutting insulation.
3) Is the Metallics KOB100 a metal or nonmetallic bushing?
Plastic, not metal. That means it is nonconductive and will not bond to the enclosure, so it serves purely as an insulating liner for the opening. If you need the fitting to carry ground continuity or secure a raceway, you want a metal connector or grounding bushing instead.
4) Will the KOB100 bushing secure conduit or cable, or is it insulation only?
Insulation only. A knockout bushing lines the hole; it does not clamp or terminate conduit or cable. For a secured entry you need a connector sized to the raceway or cable, with the KOB100 reserved for open knockouts where conductors pass through unterminated.
