Southwire 153I Bx Flex Connector Insulated 1 Inch

Product Description

The SOUTHWIRE 153I is a straight, squeeze-type BX-flex connector with an insulated throat, designed for use in electrical conduit installations. Fabricated from zinc die cast, this connector provides natural corrosion resistance and long-term durability. The insulated throat protects conductors and cable jackets from abrasion at the point of entry. A single-screw assembly design simplifies installation and reduces service time. This connector is UL listed and is installed by licensed electricians performing conduit and armored cable terminations in commercial and residential electrical work.

The 153I is used to securely join flexible metal conduit to EMT, and in dry locations it connects flexible metal conduit or armored cable to electrical boxes and enclosures. The 1 inch trade size fits standard conduit runs in both new construction and retrofit applications. This connector is suited for residential panels, commercial distribution equipment, and industrial enclosures where FMC or AC cable terminations are required in dry environments.
