Bridgeport Fittings 280SP 1/2" x 3/8" Die-Cast Zinc EMT Combination Coupling

Bridgeport Fittings 1/2" x 3/8" Die-Cast Zinc EMT Combination Coupling

Bridgeport Fittings' 1/2" x 3/8" EMT combination coupling is engineered to join electrical metallic tubing (EMT) conduit runs of two different trade sizes in a single, secure connection. Constructed from die-cast zinc for long-term corrosion resistance and mechanical strength, this combination coupling features a 1-screw set-screw connection on the 1/2" end for fast, tool-driven installation. Part of Bridgeport Fittings' Mighty-Merge® line of combination fittings, it streamlines transitions between mismatched EMT conduit sizes in commercial and industrial raceway systems. This combination coupling is designed for use wherever EMT conduit installations require a dependable transition between trade sizes without cutting or re-threading conduit.

Key Features

• Trade Size: 1/2" x 3/8" combination sizing allows electricians to transition between EMT trade sizes without additional adapters.
• Durable Construction: Die-cast zinc body construction resists corrosion and delivers long-lasting mechanical strength in conduit raceway installations.
• Set-Screw Connection: A 1-screw design secures the 1/2" EMT conduit end with a simple, tool-driven screw connection for quick, reliable installation.
• Combination Coupling Design: Purpose-built to merge two different EMT conduit trade sizes into one continuous raceway run, eliminating the need for separate reducers.
• Compact Combination Fitting: Combines two trade sizes in a single fitting, reducing the number of separate couplings and reducers needed on the job.
• Mighty-Merge® Series: Part of Bridgeport Fittings' Mighty-Merge® combination coupling line, engineered specifically for dependable trade-size transitions.
