The Arlington 505010AST is a new Snap²It® duplex connector designed for fast, secure installation of MC, AC, HCF, and flexible metal cables. This 3/4" connector comes in an open box configuration, making it convenient for contractors handling bulk installs. Made of die-cast zinc, it provides durability and corrosion resistance, with an insulated throat to protect conductors from abrasion. Its tool-free snap-in design fits directly into knockouts, streamlining the installation process. The connector supports cable diameters from 0.650" to 0.850", making it highly versatile. When taped, it forms a concrete-tight seal, ideal for residential and commercial wiring projects.
