Overview

The Hammond Manufacturing R144-321-000 is a precision-engineered steel suspension tube designed for industrial enclosure suspension systems. This 1-meter (3.28-foot) tube features a 70mm outside diameter and 62mm inside diameter, providing a robust structural core for medium to heavy-duty applications. Constructed from durable steel, it delivers superior load-bearing capacity while maintaining flexibility for system configuration. The tube is finished in RAL 7035 light gray powder coating, ensuring consistent aesthetics and corrosion resistance across Hammond’s suspension system offerings. This component integrates seamlessly with Hammond’s suspension system portfolio, including 50mm and 80mm systems, and is compatible with die-cast aluminum and cast iron fittings. Its 70mm OD specification aligns with industry standards for industrial enclosure mounting, making it ideal for NEMA 12 and NEMA 13 applications. The tube’s 62mm ID allows for cable routing and accessory mounting, while its 1-meter length provides versatility for custom installations. Built to withstand demanding environments, the R144-321-000 is a cost-effective solution for OEMs, panel builders, and system integrators requiring reliable suspension components. Pair with Hammond’s heavy-duty enclosure couplings, elbow couplings, or intermediate joints for a complete suspension framework.
