Abb 8421 Non-threaded Conduit Connector 1-1/4 Inch

Product Description

The ABB 8421 is a 1-1/4 inch non-threaded conduit connector designed to secure non-threaded conduit to enclosures, junction boxes, and panels in electrical installations. This fitting creates a reliable mechanical connection without requiring threaded conduit ends, simplifying terminations in conduit runs where threading is not practical. Electricians and electrical contractors install this type of connector in both new construction and retrofit applications. The 8421 is sized at 1-1/4 inch trade size, making it suited for medium-capacity conduit runs in commercial and industrial wiring systems.

This connector is used in commercial and industrial electrical installations where conduit must be terminated at enclosures or distribution equipment. It is appropriate for use with 1-1/4 inch non-threaded conduit in both exposed and concealed raceway systems. Typical install scenarios include panel feeders, junction box entries, and equipment connections in facilities requiring organized, code-compliant conduit routing. Licensed electricians performing conduit work to NEC standards are the primary installers of this fitting.

Key Features

• 1-1/4 inch trade size for medium-capacity conduit runs
• Non-threaded design eliminates the need for conduit threading tools at termination points
• Compatible with standard enclosures and knockout openings sized for 1-1/4 inch conduit
• Sturdy construction suitable for commercial and industrial electrical applications

Compatibility

Designed as an OEM-style fitting for use with 1-1/4 inch non-threaded conduit in standard electrical enclosures and junction boxes with appropriately sized knockouts.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize all circuits and verify the absence of voltage before beginning any conduit termination work. Ensure the knockout opening in the enclosure matches the 1-1/4 inch trade size before installing the connector. Do not overtighten the locknut or clamping mechanism, as this can deform the connector body or damage the enclosure wall.
