Eaton Crouse-Hinds CGB394 Cable Gland - 1 inch NPT 3R
Part Number: CGB394
Quick Summary
The Eaton Crouse-Hinds CGB394 cable gland provides rugged sealing for tray cables in industrial enclosures. Engineers often grapple with moisture ingress, vibration, and armoured limitations that threaten cable integrity and uptime. This gland aligns with NEC/CEC standards and carries a NEMA 3R rating for reliable protection in ordinary or non-hazardous locations, both indoors and outdoors. By supporting a 0.375-0.500 inch cable range and standard 1 inch NPT threading, it enables fast, compliant installations, reduces field rework, and delivers long-term cost savings for general-purpose wiring in demanding environments. It’s a practical choice for plant floor cabinets, control panels, and junction enclosures where reliability matters most.

FAQs
The CGB394 uses a 1 inch NPT thread, designed to mate with standard enclosure penetrations and CG fittings. This supports straightforward mounting on common electrical boxes and panels, reducing the need for adapters. The 1" NPT specification also aligns with widely stocked grommet and gland kits, simplifying procurement and on-site installation.
Yes. The CGB394 is designed for ordinary/non-hazardous locations and carries a NEMA 3R rating, which provides rain and ice protection suitable for many outdoor or semi-outdoor installations. While it is not intended for hazardous environments, its rugged steel body and weather-ready rating make it a solid choice for outdoor control panels and exposed enclosures.
The gland accommodates cable diameters from 0.375 inches to 0.500 inches, making it compatible with common tray cable sizes used in industrial automation. This range helps ensure a secure seal without excessive compression, preserving cable integrity and reducing seal failures during operation and maintenance.
The CGB394 complies with NEC/CEC standards and carries a NEMA 3R rating with an Ordinary/Non-Hazardous location classification. These certifications indicate suitability for general industrial use, weather-protected environments, and regulatory compliance for non-hazardous facilities, helping avoid compliance delays during audits and installation approvals.
Its robust steel construction, 1" NPT thread, and precise cable range reduce installation time and reseal requirements, lowering labor costs. The NEMA 3R rating enables outdoor use without additional weatherproofing, decreasing downtime during maintenance and reducing long-term replacement and warranty issues for non-armoured tray cable installations.
