EMT Set Screw Connector · 1-1/4 in Trade Size · Steel, Concrete-Tight When Taped · Bridgeport Fittings 233
What this product is for
This 1-1/4 in EMT set screw connector is used to secure electrical metallic tubing to a box or enclosure. It is a steel fitting with zinc plating and a locknut for standard EMT terminations in commercial, institutional, and industrial work.
Use for
Use for 1-1/4 in trade size EMT connections at panels, junction boxes, pull boxes, cabinets, and enclosures in dry locations. It is commonly selected where installers want a straightforward set screw connection that can be tightened with standard hand tools.
Avoid for
Avoid using this fitting where a listed raintight connector is required, or where the installation is exposed to wet locations without the appropriate fitting type. Do not assume concrete-tight performance unless installed as specified; manufacturer listings indicate concrete-tight when taped.
Best for
Best for indoor EMT runs in commercial and industrial installations where steel boxes and enclosures are used. Also suitable for maintenance, retrofit, and OEM panel work where a steel set screw connector is preferred over die-cast alternatives.
Installed in
Typically installed in dry indoor electrical rooms, service spaces, tenant fit-ups, retail units, schools, light industrial facilities, and similar applications. Fits 1-1/4 in EMT trade size conduit, approximately 31.8 mm.
Why this product exists
This connector provides a practical way to terminate EMT into a box or enclosure while maintaining mechanical retention and continuity through a standard locknut-style connection. For many indoor EMT installations, set screw fittings are a common choice because they install quickly and are easy to service.
Compared with similar products
Compared with compression EMT connectors, a set screw connector is typically faster to install and commonly chosen for dry locations. Compared with die-cast fittings, this steel body is often preferred where installers want a heavier-duty metal fitting. As a rule of thumb, EMT fill and conductor count still depend on conduit size, conductor type, and code requirements; actual installation must follow local electrical code.
