Overview

The NSi Industries 291-CDC Compression Transition Coupling is a zinc die-cast connector engineered to join 3/4-inch Rigid Metal Conduit (RMC) or Intermediate Metal Conduit (IMC) to Electrical Metallic Tubing (EMT). This coupling eliminates threading requirements with a compression design, reducing installation time while maintaining a concrete-tight seal for reliable performance in harsh environments. The ball-burnished zinc die-cast construction provides superior corrosion resistance, making it ideal for applications exposed to moisture, chemicals, or physical stress. With dimensions of 2.00 inches (A) and 1.45 inches (B), the 291-CDC supports mixed-conduit systems in power distribution, control wiring, and machinery installations. Compatible with standard 3/4-inch conduit systems, it simplifies retrofits, new construction, and maintenance projects requiring rigid-to-EMT transitions. Packaged in quantities of 15 units per box and 150 units per standard case.
  • Zinc die-cast construction with ball-burnished finish for corrosion resistance
  • Compression design eliminates threading; concrete-tight seal
  • Joins 3/4" Rigid/IMC to EMT conduit in mixed-conduit systems
  • NEMA FB-1 rated; listed for concrete-tight applications
  • Compatible with standard 3/4" conduit systems for mixed applications
