Arlington 208 3-1/2" 3-Piece Coupling for Rigid and IMC, Zinc Die-Cast

Built for fast, dependable conduit connections in demanding commercial and security installations, the Arlington Industries 3-1/2 in three-piece coupling (Part No. 208) simplifies assembly while delivering a mechanically secure join for rigid and IMC conduit. The three-piece Erickson-style design lets technicians position and tighten the coupling around installed conduits—reducing labor time and rework on retrofit or new-build projects. Constructed from zinc die-cast material, this coupling resists corrosion and stands up to repeated handling, making it a reliable choice for surveillance camera runs, monitoring networks, and general low-voltage conduit pathways.

Sized for 3-1/2 in trade conduit and engineered specifically for rigid and IMC systems, the Arlington 208 coupling provides consistent alignment and a tight fit that helps protect cabling and maintain system integrity. Its durable finish and commercial-grade construction support long-term performance in security and IT deployments. For streamlined installations and fewer on-site delays, specify the Arlington 208 three-piece coupling — order now to improve installation efficiency on your next security, surveillance, or monitoring project.
