Overview

NSi Industries 230-SBLK EMT connectors are precision steel set-screw connectors designed for 1/2" electrical metallic tubing (EMT). These color-coded connectors join EMT to enclosures or junction boxes with a concrete-tight seal, ensuring reliable performance in demanding installations. The black finish matches standard black EMT conduit, enabling quick identification in dark or open-architecture environments. Key features include Tri-Drive slot/Phillips/Robertson head screws for versatile tool compatibility and compatibility with both steel and aluminum EMT. The patented design (US Patent 6,861,585) meets Federal Specification A-A-50553 and UL Standard 514B requirements. Each connector measures 1.5" (A), 1.125" (B), and 0.875" (C) with a 1/2" trade size. The durable steel construction resists corrosion and mechanical stress, while the color-coding system reduces installation errors and speeds up assembly. Available in unit quantities of 50 and standard packages of 500.
