Southwire SB109313 3/4 Inch Nylon Knockout Bushing

Product Description

The SOUTHWIRE SB109313 is a 3/4 inch nylon knockout bushing designed to protect wire and cable insulation at conduit knockouts in electrical enclosures, panels, and junction boxes. Made from nylon, this bushing snaps into a standard 3/4 inch knockout opening to create a smooth, rounded edge that prevents abrasion damage to conductors pulled through the opening. Electricians use this fitting during panel rough-in and finish work wherever a conduit connector is not installed but wire protection at the knockout is still required by code.

This bushing is suited for residential and light commercial electrical installations. It fits standard 3/4 inch knockout openings found in load centers, sub-panels, junction boxes, and enclosures. The nylon construction resists corrosion and is appropriate for dry and damp indoor locations. It is a common stock item for service electricians and electrical contractors who regularly work with wire management and panel terminations.

Key Features

• 3/4 inch size fits standard knockout openings in electrical enclosures and panels
• Nylon construction provides insulation protection against sharp metal knockout edges
• Snap-in installation requires no tools and seats securely in the knockout

Compatibility

Installation Notes

Installation is performed by licensed electricians. Always de-energize and lock out the panel or enclosure before servicing any knockout opening. The bushing snaps into the knockout by hand with no special tools required. Verify compliance with applicable NEC requirements for conductor protection at enclosure openings before closing up the box.
