Feature: Through-hole mounting simplifies attachment to frames and enclosures, reducing hardware choices and misalignment risks. Business impact: Faster, error-free installation translates to shorter project schedules and lower field labor costs. Application: Ideal for complex automation panels where consistent mounting geometry is essential for clean, predictable cable routing and easier future upgrades within the Eaton B-Line ecosystem. This reduces field modifications and rework during panel upgrades. Feature: No knockouts on the ends with a secure screw-cover design minimize dust ingress and accidental cable movement. Business impact: Enhances long-term reliability and reduces maintenance interruptions. Application: Well-suited for indoor machine enclosures with high vibration or frequent servicing, where enclosure integrity matters. In addition, the end-seal design supports clean internal cable separation. Feature: 16 gauge steel construction finished in ANSI 61 gray delivers rigid protection and a durable aesthetic. Business impact: Increased resistance to impact and corrosion extends service life in busy manufacturing environments. Application: Suitable for factory floors, robotics cells, and control panels requiring durable, standardizable components. Its standardization with other B-Line products enhances interchangeability. Feature: 4 in height, 4 in width, 18 in length with NEMA 1 protection. Business impact: Predictable footprint simplifies layout planning and reduces custom fabrication. Application: Ideal for compact enclosures and modular builds with consistent part compatibility across the Eaton B-Line line. Engineers benefit from consistent bolt patterns and reduced need for rework. Feature: Plated screws secure the cover, ensuring a tight seal during vibration and cleaning. Business impact: Improves enclosure integrity and reduces re-termination risk. Application: Effective in environments with frequent access to wiring or where long-term reliability is required. The screw cover design also simplifies inspections. Feature: CSA Certified and UL Listed for trusted electrical safety; compatibility with B-Line accessories ensures scalable routing. Business impact: Streamlines approvals and enables quick system expansion. Application: Ideal for facilities pursuing standardization and rapid integration of new wiring runs. This makes legacy installations easier to upgrade.

Yes. The enclosure is CSA Certified and UL Listed, providing recognized safety and performance for electrical assemblies. The NEMA 1 steel construction with ANSI 61 gray finish offers indoor protection, while the 16 gauge thickness provides stiffness for vertical and horizontal runs. Verify local codes for any additional certifications your project may require.
Key dimensions are 4 inches in height and width, and 18 inches in length, confirming a compact 4x4x18 inch footprint. The unit weighs about 4.964 pounds and uses 16 gauge steel with ANSI 61 gray finish. These specs help with space planning and determine mounting clearance in tight enclosures.
Industries focused on reliable, room-efficient panel wiring benefit most, including machine builders, automation integrators, and process manufacturers. The 4418 G NK supports clean, protected cable routing in indoor control cabinets and equipment housings. Its NEMA 1 rating and steel construction make it a practical choice for steady, climate-controlled environments where standardization matters.
Compared with knock-out versions, the 4418 G NK ends are closed with a screw-cover, reducing dust ingress and simplifying routing. The ANSI 61 gray finish matches common factory aesthetics and provides a consistent look across installations. For higher protection or outdoor use, select alternative enclosures with greater ratings and verify compatibility.
