Eaton Specification Sheet - GRFX339 HDG
Industrial Fittings Bend Radius and Cubic Capacity Chart
Feature → Business Impact → Application: The GRFX339 HDG uses a Feraloy iron alloy with a hot-dip galvanized finish, delivering exceptional corrosion resistance in demanding environments. This directly reduces maintenance cycles and extends service life for outdoor or moisture-prone installations, improving overall equipment uptime in plant floors and outdoor enclosures. Application: ideal for surface-mounted Condulet GRF implementations on walls or equipment housings in ordinary-location facilities. Feature → Business Impact → Application: Four hubs and three plugs provide flexible conduit entry and sealing, enabling tidy wire management and scalable expansions. This minimizes field rework and enables faster wiring than alternative box configurations. Application: suitable for control panels and industrial machines requiring reliable conduit distribution with unused entries sealed cleanly. Feature → Business Impact → Application: A 1 inch tap size supports standard fittings, simplifying sourcing and compatibility with common conduit components. Application: beneficial in retrofit projects or new builds where quick integration with existing conduit runs is desired. Feature → Business Impact → Application: Surface mounting capability reduces install time and mounting hardware needs, improving installation efficiency on varying substrates. Application: supports on-wall installations in constrained layouts. Feature → Business Impact → Application: Blank back boss accommodates future customization or expansion, enabling phased upgrades without replacing the enclosure. Application: ideal for evolving control architectures in industrial automation environments.

FAQs
GRFX339 HDG supports standard conduit fittings through its 4 hub entries and 3 plug locations, plus a 1 inch tapped connection. The surface-mount design simplifies integration with existing GRF Condulet systems and allows straightforward wiring in ordinary-location environments. The blank back boss enables future customization without replacing the enclosure.
The 3-1/8 inch inside depth provides ample room for multi-conductor wiring and strain relief, while the 1 inch tap supports common conduit fittings. This combination reduces wiring crowding, minimizes splices, and accelerates installation, contributing to shorter project timelines and easier maintenance in control panels and machine enclosures.
Best applications include industrial control panels, machine enclosures, and outdoor equipment in ordinary/non-hazardous locations. The surface-mount GRF design, combined with robust corrosion resistance from Feraloy iron alloy and hot-dip galvanized finish, makes it ideal for environments with moderate exposure to moisture and mechanical vibration where reliable conduit connections are essential.
This GRF tapped outlet box is designed to NEC/CEC-compliant, Ordinary/Non-Hazardous Locations, and UL-listed conformance. These certifications support regulatory inspections, safety audits, and cross-border project approvals, reducing compliance risk and streamlining procurement for facilities aiming to meet national electrical codes and standards.
The rugged Feraloy iron alloy with hot-dip galvanizing offers long-term corrosion resistance, reducing replacement and maintenance costs. Its 4 hubs and 3 plugs lower field rework, while surface mounting speeds installations. Over project lifecycles, this translates to less downtime, lower total cost of ownership, and faster deployment in new or retrofit industrial automation projects.
