Overview

The NSi Industries 655-DC2 is a 3/4" flexible metal conduit (FMC) two-screw strap type connector engineered for secure, vibration-resistant connections between FMC and electrical enclosures or junction boxes. Constructed from high-strength zinc die-cast material with a ball-burnished, mirror-smooth finish, this connector delivers superior corrosion resistance and long-term durability in industrial and commercial environments. Designed for conduit sizes ranging from 6/3 to 4/3 AWG (0.85" to 1.10" outer diameter), the 655-DC2 ensures a tight, reliable grip critical for AC, MC, and FMC installations where stability under vibration is essential. The two-screw strap design provides consistent clamping force, preventing conduit pull-out and maintaining electrical continuity. Precision-engineered with dimensions of 1-3/4" (A), 1/2" (B), 1-5/8" (C), 1-7/14" (D), and 13/16" (E), this connector is fully compatible with standard 3/4" FMC systems. Its zinc die-cast construction meets Federal Specification A-A-50552, NEMA Standard FB-1, and UL Standard UL514B, ensuring reliable performance in demanding applications. The ball-burnished finish enhances corrosion resistance while providing a professional appearance.
