Arlington Industries 4491 Non-Metallic Insulating Bushing with Insulated Throat, 5" Trade Size

Arlington Industries Non-Metallic Insulating Bushing with Insulated Throat, 5" Trade Size

The Arlington Industries non-metallic insulating bushing is engineered for the 5" trade size, designed to thread onto the end of conduit runs and protect conductor insulation as wires pass through the fitting. Molded from durable, non-conductive plastic, this insulating bushing features an insulated throat that shields cable jacketing from abrasion against sharp conduit edges during and after installation. Because the body is non-metallic, this bushing provides electrical isolation at the conduit termination point rather than conducting current the way a metallic bushing would. Electrical contractors specify insulating bushings like this one to help protect wire insulation and maintain a clean, code-compliant conduit termination in commercial and industrial electrical systems.

Key Features

• Trade Size: Sized for the 5" trade size conduit, providing a secure thread-on fit at the conduit termination point.
• Durable Construction: Non-metallic, plastic body resists corrosion and will not conduct electrical current, unlike metallic bushing alternatives.
• Insulated Throat: The insulated throat design guards conductor insulation from cuts and abrasion as wires are pulled through the conduit end.
• Threaded Bushing: Installs directly onto threaded conduit ends for a quick, tool-friendly connection.
• Electrical Isolation: The non-conductive plastic body helps isolate the conduit end and prevents metal-to-metal contact at the termination point.
• Corrosion Resistant: Non-metallic plastic construction will not rust or corrode, unlike steel or malleable iron bushings.
