Thomas Betts 259 Fmc Conduit Connector 2 Inch

Product Description

The THOMAS BETTS 259 is a straight, non-insulated conduit connector designed for use with flexible metal conduit (FMC). Built from malleable iron, it uses a squeeze clamp connection method to secure the conduit end to an enclosure or junction box knockout. The 259 carries a 2-inch trade size rating and is listed for use in hazardous locations, making it suitable for industrial and commercial installations where code compliance in classified areas is required. Electrical contractors and licensed electricians install this fitting as part of a complete FMC termination in panel, motor, or equipment connections.

This connector is used in commercial and industrial electrical systems where flexible metal conduit must be terminated at enclosures, motor junction boxes, or control panels. Its hazardous location rating makes it appropriate for areas classified under NEC Article 500, including facilities such as refineries, chemical plants, grain handling operations, and similar environments. The straight body profile suits standard 90-degree or in-line terminations where the conduit approaches the knockout directly.

Installation Notes

Installation of this fitting is typically performed by a licensed electrician. Before installing or servicing any conduit fitting, de-energize the circuit at the panel and verify with a meter that no voltage is present. Ensure the knockout diameter matches the 2-inch trade size of the connector before installation. In hazardous locations, verify that the complete installation assembly meets all applicable NEC and local code requirements for the specific location classification.
