The 90° angle design reduces bending and routing complexity in tight panel spaces, delivering faster installations and cleaner wiring layouts, which translates to lower labor costs and fewer field errors. The zinc die cast construction provides rugged durability against industrial vibration and impact, extending device life in demanding environments and lowering replacement frequency. With a 1/2" trade size, the connector fits standard armor profiles, enabling straightforward compatibility with common AC/MC and FMC cables and minimizing the need for adapters or re-termination. NEC/CEC compliance ensures code-conformant terminations, reducing audit issues and streamlining inspections across projects. Area classification of Ordinary/Non-Hazardous Locations expands usable applications, supporting safer, non-hazardous installations without special enclosures. The Quick-Lok Pro family is designed for fast field assembly, which boosts installation efficiency and helps procurement plans meet tight schedules. Compatibility with both AC/MC and FMC cables minimizes inventory complexity and supports a unified conduit strategy across future deployments.
