The NESCO Model 158Z is a 3-inch zinc squeeze connector engineered for professional electricians and contractors who demand reliable, code-compliant connections between flexible metal conduit (FMC) and electrical enclosures. Built with a robust zinc die-cast body, this connector delivers solid mechanical grip and dependable electrical continuity — ideal for commercial, industrial, and residential job sites where FMC terminations need to hold up under vibration, repeated handling, and demanding installation conditions. Its squeeze-style design speeds up installation without sacrificing pull-out strength, making it a go-to choice for panel rough-ins, motor connections, and equipment hook-ups.
