Bridgeport Fittings 4357-DC Mighty-Merge EMT to Triple AC/FMC Combination Coupling, 1" to 3/8"

Bridgeport Fittings 4357-DC Mighty-Merge EMT to Triple AC/FMC Combination Coupling, 1" to 3/8"

The Bridgeport Fittings 4357-DC Mighty-Merge Combination Coupling transitions a single 1" EMT conduit run into three separate 3/8" connections for AC (armored cable) or FMC (flexible metal conduit), all in one compact fitting. Designed for electricians who need to consolidate multiple flexible cable or conduit runs into a single EMT raceway, this Mighty-Merge coupling simplifies wiring at panels, junction boxes, and equipment connections. The 1" to 3/8" transition design reduces the number of individual fittings and knockouts required for multi-circuit installations.

Key Features

• Trade Size Transition: Combines a 1" EMT trade size on one end with three individual 3/8" connections on the other end.
• Triple Outlet Design: Provides three separate 3/8" ports for AC or FMC cable, allowing multiple flexible runs to feed into a single EMT conduit.
• Mighty-Merge Combination Coupling: Purpose-built to merge EMT conduit with AC or FMC cable in one fitting, eliminating the need for separate couplings and connectors.
• Installation Flexibility: Each 3/8" outlet accepts either AC or FMC cable, giving installers flexibility to match the cable type used on the job.
• Space-Saving Fitting: Reduces box fill and panel congestion by consolidating three cable connections into a single 1" EMT entry point.
• Streamlined Installation: A single Mighty-Merge fitting replaces multiple standalone couplings and connectors, saving labor time on the job site.
