Eaton Specification Sheet - CGB399 SA
Feature: 1 in NPT threaded connection with a non-armoured gland body. Business Impact: Delivers a secure, leak-free termination that resists loosening under vibration on busy production lines. Application: Ideal for tray cables (non-armoured) terminating into electrical enclosures and panels. Feature: Aluminum gland housing provides corrosion resistance and light weight. Business Impact: Reduces installation effort and lifecycle costs while maintaining mechanical strength. Application: Suited for damp or outdoor environments where aluminum performs well. Feature: Cable range 1.000–1.188 in aligns with standard tray cable diameters. Business Impact: Ensures proper seal and strain relief, reducing the need for multiple gland sizes and extra inventory. Application: Streamlines procurement for OEMs and field installers. Feature: NEC/CEC compliance and NEMA Rating 3R 4X. Business Impact: Aids regulatory approvals and reliability in harsh environments. Application: Appropriate for ordinary/non-hazardous locations in enclosures and outdoor-rated installations. Feature: Compact dimensions and weight (3.21 in L, 2.25 in W, 0.46 lb). Business Impact: Improves fit in tight spaces and reduces handling; lowers shipping and installation time. Application: Beneficial for retrofit projects and panel builds requiring a compact gland.

FAQs
For proper installation, use the 1NPT threaded entry to mate the gland to compatible enclosure openings. Verify the cable diameter falls within the 1.000–1.188 in range and secure the gland with appropriate torque to maintain the seal. The non-armoured design is intended for tray cables, minimizing compatibility issues with armoured conductors.
The gland supports cables from 1.000 to 1.188 inches in diameter. This range ensures a tight compression and proper seal with non-armoured tray cables, reducing ingress risk. Selecting within this range avoids over-compression or under-sealing, which can compromise enclosure protection.
Yes. The gland is designed for ordinary/non-hazardous locations and carries NEC/CEC compliance with a NEMA 3R 4X rating, providing weather and corrosion resistance. It is ideal for control panels and enclosures in general manufacturing environments where hazard exposure is low.
The CGB399 SA adheres to NEC/CEC standards and carries a NEMA 3R 4X rating, indicating suitability for indoor and outdoor use in non-hazardous settings. This supports regulatory approvals, safety, and long-term reliability, reducing project risk during design reviews and procurement.
Aluminum construction offers corrosion resistance with light weight, improving installation ease and reducing labor costs. The non-armoured design minimizes material complexity, while the 1NPT thread and standardized cable range streamline stocking and replacements, delivering lower total cost of ownership over the gland’s service life.
