Bridgeport Fittings 5157-DC Mighty-Merge EMT to Two AC Coupling, 3/4" to 3/8" Compression Nut, Die-Cast Zinc

Bridgeport Fittings 5157-DC Mighty-Merge EMT to Two AC Coupling, 3/4" to 3/8" Compression Nut, Die-Cast Zinc

The Bridgeport Fittings 5157-DC Mighty-Merge coupling is a die-cast zinc combination fitting engineered to join 3/4" EMT conduit to two separate AC or MC cable runs through 3/8" compression nuts. Designed for electricians who need to consolidate conduit and armored cable connections at a single point, this Mighty-Merge coupling reduces the number of individual fittings required in a box or enclosure, saving both space and installation time. Its rugged die-cast zinc body delivers the strength and corrosion resistance professional installers expect from Bridgeport Fittings products, making it a practical solution for jobs that mix EMT and AC/MC wiring methods.

Key Features

• Trade Size: 3/4" EMT connection transitions to two 3/8" compression nut outlets for AC/MC cable connections.
• Durable Construction: Die-cast zinc body resists corrosion and provides long-lasting mechanical strength for demanding job-site conditions.
• Mighty-Merge Design: Combines one EMT conduit termination with two separate AC/MC cable connections in a single fitting, simplifying box fill and reducing installation time.
• Compression Nut Connection: 3/8" compression nuts secure armored cable connections for a tight, reliable termination at each outlet.
• Space-Saving Combination Fitting: Eliminates the need for multiple standalone connectors when merging EMT and AC/MC wiring methods in the same box.
• Compact Combination Body: Consolidates conduit and cable transitions into one die-cast fitting, saving valuable space inside boxes and enclosures.
• Professional-Grade Zinc Alloy: Die-cast zinc alloy construction is engineered for durability in commercial and industrial electrical installations.
