Overview

The ABB AL21/050/A/BLUS Straight Conduit Fitting is a precision-engineered industrial-grade solution for secure conduit connections in electrical installations. Manufactured by ABB - Installation Products, this fitting features a fixed external male thread with a 1/2" National Pipe Thread (NPT) configuration, ensuring compatibility with standard threaded conduit systems. The nominal conduit size of 21mm accommodates common industrial conduit dimensions, providing a seamless fit for reliable installations. Engineered for harsh environments, this black conduit fitting is constructed from durable materials to withstand exposure to moisture, chemicals, and mechanical stress. The absence of a locknut simplifies installation while maintaining a robust connection, reducing labor time and minimizing potential failure points. This design is ideal for applications requiring quick, reliable conduit routing without additional securing hardware. Key specifications include: - SKU: AL21/050/A/BLUS - Conduit size: 21mm (nominal) - Thread type: 1/2" NPT male - Material: High-strength steel with black finish - Hazardous location suitability: Class I Div. 2; Class II Div. 1 & 2; Class III Div. 1 & 2 per NEC standards - Country of origin: US The fitting is suitable for use in hazardous locations where general-purpose equipment is permitted per NEC Section 500-2(a).
