Feature Summary

• Constructed from painted steel with a surface gray finish for indoor durability
• Features a hinged cover design for accessible maintenance and installation
• Includes mounting holes on the back panel for secure attachment
• Equipped with various size knockouts on each side for cable management

Applications

• Indoor electrical panel assembly integration
• Grounding distribution within industrial enclosures
• Cable routing and management in control systems

Procurement Notes

Verify that the application environment remains indoors, as the Type 1 rating does not support outdoor exposure or environmental sealing. Confirm that the required cable entry points align with the available knockout sizes on the sides of the trough. Ensure compatibility with the specific enclosure model intended for integration, as dimensions must match the housing constraints. Check for any regional compliance requirements regarding the steel material composition and paint finish specifications.

Selection Notes

Select this component when a grounded cable management solution is required for indoor panels. The 60-inch length provides substantial routing capacity for multiple conductors. Consider the inclusion of the single-point ground lug as a critical feature for safety compliance. Evaluate whether the standard hinge mechanism meets the operational frequency requirements of the installation site. Verify that the surface gray finish is acceptable for the visual standards of the facility.

Part Context

This splitter trough belongs to the Hoffman Type 1 series, designed for general indoor use where protection against falling objects and limited ingress of solid foreign bodies is sufficient. It serves as an accessory to main enclosures, providing organized pathways for cables and grounding connections.
