FAQs
The NPL350400SA is designed for rigid-IMC conduit connections in industrial environments and uses aluminum construction for lightweight, durable performance. It fits standard 3-1/2 in size and 4 in length requirements common in control panels and mechanical rooms.
Yes. The product specifies NEC/CEC standards with an Ordinary/Non-Hazardous area classification, ensuring code-compliant operation in typical facilities without hazardous environments.
Best used in industrial electrical wiring and automation panels where rigid/IMC aluminum fittings provide a secure connection, lightweight handling, and code-compliant performance in non-hazardous locations.
Plan for compatible locknuts and washers, use appropriate threading, and ensure the 4 in length integrates with your 3-1/2 in conduit runs. Aluminum construction aids handling, but verify environmental exposure beyond ordinary locations.
