Feature Summary

• Constructed from steel with a gray painted finish
• Features unique keyhole screw slots for simplified installation

Procurement Notes

Verify that the base pull box dimensions match the 10x10 inch requirement before procurement. Confirm that the application environment aligns with NEMA 1 and IP30 ratings, as this unit is not suitable for outdoor or wet locations. Ensure compatibility with existing Type 1 accessories if integrated into a larger assembly. Check for included mounting hardware to avoid separate sourcing.

Selection Notes

Select this extender when additional depth is required for a 10x10 inch steel pull box without altering the external footprint. It is appropriate for indoor environments where protection against solid objects and dripping non-corrosive liquids is sufficient. Consider this option over custom fabrication for standardized replacement or expansion needs within Type 1 rated systems.

Part Context

This component belongs to the nVent Hoffman line of enclosure accessories, specifically designed to modify existing pull boxes. It serves as an extension piece rather than a standalone enclosure, allowing users to increase internal space while maintaining the structural integrity and rating of the original housing. It complements the broader range of Hoffman enclosures by offering modular expansion capabilities.

Replacement Considerations

No public confirmed substitute part numbers are available for this specific extender model.
