Eaton Specification Sheet - B494-18ZN
Feature → Business Impact → Application: Braced single bracket design improves load distribution and rigidity, reducing sag and misalignment in B42 channel applications. This translates to longer service intervals and less field tuning, especially in high-vibration environments common in manufacturing floors. Use in electrical rack systems to simplify mounting of panels and components while maintaining consistent beam alignment. Feature → Business Impact → Application: Electro-plated steel finish delivers corrosion resistance, extending life in damp or industrial atmospheres and lowering maintenance costs. Apply in outdoor or damp interior spaces where exposure to moisture is a concern, such as data centers with humid environments or wash-down zones. Feature → Business Impact → Application: 18 in length with 8.75 in height and 1.62 in width provides a compact yet sturdy form factor, enabling precise siting within tight panels or enclosures. Ideal for retrofit projects or new builds where space is constrained but structural support must remain solid. Feature → Business Impact → Application: Bottom brace B42 channel compatibility ensures secure anchoring in common Eaton channel systems, simplifying inventory management and on-site installation. This reduces SKU proliferation and accelerates project delivery for contractors and integrators. Feature → Business Impact → Application: Electro-plated finish and steel construction deliver dependable mechanical strength without excessive weight, supporting faster installation and safer handling by technicians. Use when handling and positioning heavy components in crowded racks, minimizing the risk of dropped parts and rework. Feature → Business Impact → Application: Overall geometry and mounting geometry align with Channel Nuts and Hardware Catalog references, enabling straightforward integration with standard fittings and accessories for scalable upgrades across facilities. This supports future-proofed layouts and easier upgrades for growing systems.

It supports standard channel hardware and aligns with Eaton’s B-Line accessories catalog, simplifying ordering and on-site compatibility. This compatibility reduces field modification time and ensures load paths remain consistent with channel-based framing.
Plan for a secure mounting to a B42 channel using compatible hardware from Eaton’s catalog. The bracket measures 18 inches in length, 8.75 inches in height, and 1.62 inches in width, with a steel, electro-plated finish for corrosion resistance. Consider enclosure height and any nearby components to ensure proper clearance and alignment before tightening fasteners.
Yes. The bracket is intended for channel-based rack systems and electrical enclosures, offering robust steel construction and an electro-plated finish. Its dimensions and bottom-brace design support stable panel mounting in environments where vibration, moisture, or dust may impact less-reinforced hardware, contributing to longer service life and fewer adjustments after installation.
The product listing notes Certifications as Not Applicable. While formal SIL, CE, or IP ratings are not specified, the bracket’s electro-plated steel and compatible B42 channel design provide durable performance for standard industrial installations. For regulated environments, verify with your site’s compliance requirements and consult Eaton’s specification sheet for detailed material and finish data.
Anticipate ROI from reduced installation time, fewer field modifications, and lower maintenance due to corrosion-resistant electro-plated steel. The 18 in by 8.75 in by 1.62 in footprint fits compact rack spaces, enabling faster upgrades and scalable assemblies. The compatibility with existing Eaton channel hardware minimizes part variety, streamlining procurement and project scheduling.
