Eaton Crouse-Hinds CGB399 SG Cable Gland - NEC/CEC
Part Number: CGB399 SG
Quick Summary
CGB399 SG cable gland provides a reliable sealing solution for non-armoured tray cables used in general-purpose electrical installations. Many engineers struggle with selecting the correct gland size, achieving IP/Ingress protection, and coordinating the seal, locknut, and mounting hardware in tight spaces. UL certification, NEC/CEC compliance, and a NEMA 3R rating give you confidence in safety, regulatory alignment, and outdoor or indoor rugged applications. Designed in steel and featuring a sealing gasket and locknut, it simplifies installation, ensures consistent sealing across temperatures, and reduces rework. With compatibility for 1" NPT threads and non-armoured tray cables, it supports fast commissioning, lowers maintenance costs, and improves overall system reliability.

Eaton Specification Sheet - CGB399 SG
Steel construction delivers rugged mechanical protection for general-purpose cable glands used with non-armoured tray cables. The robust format stands up to factory-floor vibration, incidental impact, and temperature cycling, reducing replacement and maintenance costs. This durability translates into longer service life and less downtime in critical wiring installations. Cable range and threading specifications ensure a precise fit across a narrow wire pairing window. The gland accommodates 1.000–1.188 in cables with a 1" NPT thread, minimizing field adjustments and rework. Fast, predictable installation supports electricians and procurement teams by reducing material variance and inventory complexity. Sealing gasket and locknut are included as standard accessories, enhancing sealing integrity and simplifying assembly. This combination provides reliable ingress protection and reduces call-backs for moisture or dust ingress. The kit-friendly design supports quick retrofits and consistent performance across temperature ranges. Certifications and compliance underpin risk management for regulated facilities. UL certification, NEC/CEC compliance, and a NEMA 3R rating confirm suitability for ordinary/non-hazardous locations and outdoor exposure when paired with compatible enclosures. This aligns with plant, data-center, and industrial facility policies by avoiding incidental non-conformance. Application versatility and ease of use: tray cable glands like the CGB399 SG integrate with Eaton Crouse-Hinds CG fittings family, ensuring compatibility across installations, spare parts, and service fleets. The result is faster project turnover, lower total cost of ownership, and a standardized approach to cable entry management.
