SEPCO S1110 Zinc-Plated Steel EMT Set-Screw Conduit Connector, 1/2" - 4"

SEPCO S1110 Zinc-Plated Steel EMT Set-Screw Conduit Connector, 1/2" to 4"

The SEPCO S1110 is a zinc-plated steel EMT set-screw connector engineered to terminate Electrical Metallic Tubing (EMT) conduit runs at boxes, panels, and enclosures across commercial and industrial wiring systems. This connector is available in trade sizes ranging from 1/2" to 4", covering the full range of EMT conduit sizes electricians encounter on the job site. The steel body delivers the mechanical strength expected of a quality conduit fitting, while the zinc-plated finish helps resist corrosion from routine job-site handling, storage, and everyday installation conditions. A set-screw connection method lets installers create a secure, tool-tightened mechanical joint between EMT conduit and the enclosure without soldering, giving electrical contractors a dependable, easy-to-install option across every trade size in the S1110 line.

Key Features

• Trade Size Range: Available in trade sizes from 1/2" to 4" to match a wide range of EMT conduit runs.
• Durable Construction: Zinc-plated steel body combines the mechanical strength of steel with added corrosion resistance for long-term reliability in EMT conduit installations.
• Set-Screw Connection: Set-screw design allows a secure, tool-tightened mechanical connection between EMT conduit and the connected box, panel, or enclosure, without soldering.
• EMT Compatibility: Purpose-built connector for Electrical Metallic Tubing (EMT), designed to terminate tubing cleanly and squarely at the connection point.
• Straight Connector Configuration: Joins EMT conduit runs to boxes, panels, and enclosures in a raceway system.
• Zinc-Plated Finish: Plated finish helps protect the steel body from corrosion during storage, handling, and installation, extending service life.
• Job-Site Ready: Steel-and-zinc construction is sized to hold up to the wear and tear of everyday electrical rough-in and finish work across every trade size in the range.
