Overview
The SEPCO S1114 is a 3/4-inch set screw coupling engineered for secure connection and grounding of EMT (electrical metallic tubing) raceway sections. This zinc-plated steel coupling delivers reliable performance in electrical installations where tight, permanent connections are required. The concrete-tight design ensures consistent grounding continuity across connected conduit runs.
Key Features
- Zinc-plated steel construction — resists corrosion in indoor and light outdoor environments
- Concrete-tight coupling — engineered for secure, moisture-resistant connections
- 3-Way combination screws — accommodate various screw types for installation flexibility
- Set screw connection — simple, tool-free assembly without special equipment
- UL/cULus listed — meets recognized safety standards for electrical applications
- Box of 25 units — convenient quantity for standard projects or stocking
