Southwire 157 2.5 Inch Flex Bx Squeeze Connector

Product Description

The SOUTHWIRE 157 is a squeeze-type connector designed for terminating 2.5-inch flexible metal conduit (FMC) and BX armored cable at enclosures, junction boxes, and panels. Squeeze connectors use a simple screw-actuated clamping mechanism that compresses around the conduit or cable armor without requiring specialized tools, making them a fast and reliable choice for field terminations. Licensed electricians and electrical contractors install this fitting as part of branch-circuit and equipment-connection wiring where flexible conduit sections transition to a fixed enclosure. The connector is sized for 2.5-inch trade-size conduit and weighs 9 pounds per package quantity.

The SOUTHWIRE 157 is suited for commercial and industrial electrical installations where flexible metal conduit or armored cable must be secured to a metal knockout. Common applications include motor connections, HVAC equipment whips, and other wiring runs that require a degree of vibration isolation or repositioning flexibility. The squeeze design allows quick one-handed positioning before final tightening, speeding up repetitive installation work on large projects.

Key Features

• Squeeze-type clamping mechanism — no specialty tools required for installation
• Sized for 2.5-inch trade-size flexible metal conduit and BX armored cable
• Designed for termination at standard metal knockouts on enclosures and junction boxes
• Suitable for motor, HVAC equipment, and branch-circuit flexible conduit terminations

Compatibility

Designed as an OEM-style replacement fitting for 2.5-inch trade-size flexible metal conduit and BX armored cable termination applications in commercial and industrial electrical installations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements for flexible metal conduit terminations. De-energize and lock out the circuit or equipment before making any conduit connections at an enclosure or panel. Seat the connector fully into the knockout and tighten the locknut securely before tightening the squeeze screw onto the conduit or cable armor. Do not overtighten the clamping screw in a way that deforms the conduit or compromises the armor integrity.
