EMT Set Screw Connector · 3/4 in · Steel Zinc-Plated · Bridgeport Fittings 231-US
What this product is for
This 3/4 in EMT set screw connector is used to terminate electrical metallic tubing (EMT) into a box or enclosure. It is a steel, zinc-electroplated fitting with a locknut for standard EMT raceway work.
Use for
Use for 3/4 in EMT connections in commercial, institutional, and light industrial installations where EMT needs to be secured to a cabinet, junction box, pull box, or enclosure. It is commonly selected for indoor raceway work and can be installed as concrete-tight when taped, per manufacturer literature.
Avoid for
Avoid using this fitting where a raintight or wet-location connector is required, or where an insulated throat connector is specified for conductor protection. For outdoor wet locations, washdown areas, or corrosive environments, choose a listed fitting intended for those conditions.
Best for
Best for electricians and contractors who need a standard steel EMT box connector in 3/4 in trade size with familiar set screw installation. It suits routine branch circuit and feeder raceway terminations where steel construction and UL 514B listing matter.
Installed in
Typically installed in electrical rooms, service spaces, commercial tenant fit-outs, retail spaces, schools, warehouses, and industrial control or distribution enclosures. Trade size is 3/4 in, approximately 19 mm.
Why this product exists
This connector provides a simple mechanical termination between EMT and an enclosure without threading the conduit. The set screw design speeds installation and is widely used for dry-location EMT systems.
Compared with similar products
Compared with compression EMT connectors, set screw connectors are typically chosen for straightforward indoor work and faster installation. Compared with insulated-throat versions, this model is non-insulated, so buyers should confirm whether conductor protection requirements or project specs call for an insulated throat.
Typical trade guidance: 3/4 in EMT is commonly used where more conductor capacity is needed than 1/2 in raceway can comfortably provide. Actual conduit fill depends on conductor size, insulation type, fitting selection, and local electrical code.
