ALEX® Steel EMT Set Screw Couplings are designed to join two sections of Electrical Metallic Tubing (EMT) quickly and securely. Their set-screw fastening mechanism provides a firm and stable connection, ensuring proper alignment and continuity throughout the conduit run.
Constructed from heavy-duty steel, these couplings offer superior mechanical strength and long-term performance in demanding electrical environments. The corrosion-resistant finish enhances durability, making them suitable for commercial, industrial, and residential wiring systems.
Each coupling is precision-formed and quality-checked at ALEX’s manufacturing facility to ensure consistent fit, reliable grounding, and compatibility with standard EMT conduit sizes.
