Bridgeport Fittings SB-388NM 3 in Nonmetallic Split Bushing

Product Description

The BRIDGEPORT FITTINGS SB-388NM is a 3-inch insulated nonmetallic split bushing designed to protect conductors passing through conduit openings and to terminate rigid conduit, IMC conduit, or EMT connectors to a box or enclosure. Manufactured from gray plastic, the bushing features a 2.14-inch diameter and is heat rated to 105 degrees C. Its split design allows installation before or after conductors are pulled, making it practical for retrofits and upgrades on existing power and data systems without requiring full conductor removal.

This bushing is suited for use in commercial and industrial electrical installations where conductor protection at conduit terminations is required. It is appropriate for new construction and retrofit applications alike, particularly where minimizing facility downtime during upgrades to power distribution or data infrastructure is a priority. Licensed electricians and electrical contractors are the primary installers of this fitting.

Key Features

• Split design allows installation with conductors already in place, reducing downtime on retrofit jobs
• Heat rated to 105 degrees C for use in higher-temperature environments
• 2.14-inch bushing diameter provides a defined conductor protection surface
• Nonmetallic gray plastic construction resists corrosion
• OSHA-recognized, NRTL-listed to meet construction and general industry electrical standards
• Compatible with rigid conduit, IMC conduit, and EMT connector terminations to boxes or enclosures

Compatibility

Designed for use with 3-inch rigid conduit, IMC conduit, and EMT connectors terminating to a box or enclosure. Suitable for both new construction and retrofit conductor protection applications.

Installation Notes

Installation is performed by a licensed electrician in accordance with applicable NEC requirements. De-energize all circuits before beginning work on any conduit termination or enclosure entry point. The split bushing snaps into place at the conduit end and does not require special tooling, but verify the bushing is fully seated before pulling or securing conductors. Do not use this nonmetallic fitting as a grounding or bonding continuity path.
