Thomas & Betts 3213 Knockout Bushing One And A Quarter Inch

Description:

The Thomas & Betts 3213 Knockout Bushing is used to protect conductors from abrasion when passing through 1-1/4 inch knockout openings in metal boxes, cabinets, and electrical enclosures. Commonly installed in industrial control panels, switchgear, junction boxes, motor control centers, and commercial electrical distribution systems, this one-piece thermoplastic bushing snaps securely into knockout openings to provide a smooth, insulated edge for Rigid and IMC conduit installations. Electricians, panel builders, and maintenance personnel use this bushing for new installations, repairs, retrofits, and replacement of electrical enclosure protection components.

Applications:

The Thomas & Betts 3213 is designed for insulating and protecting conductors passing through metal knockout openings. It is ideal for use in electrical panels, junction boxes, switchboards, control cabinets, and equipment enclosures where Rigid or IMC conduit is installed. The snap-in design provides quick installation while reducing the risk of conductor insulation damage caused by sharp metal edges.
