A30304SUG

Overview

The Hoffman A30304SUG is a screw-cover pull box extender designed for Type 1 applications. Constructed from galvanized steel, it measures 30 inches in height, 30 inches in width, and 4 inches in depth (762mm x 762mm x 102mm). This component fits existing 30x30 inch steel pull boxes to create additional wiring space. It does not include a back panel.

Feature Summary

• Galvanized steel construction for corrosion resistance
• Screw-cover design compatible with standard Type 1 enclosures
• Extends internal volume of existing 30x30 inch pull boxes

Applications

• Power distribution systems requiring expanded wire management
• Industrial electrical installations needing additional conduit entry points
• Retrofitting existing pull boxes with increased capacity

Procurement Notes

Verify that the target enclosure matches the 30x30 inch dimension requirement. Confirm that the application requires a Type 1 rating. Ensure the order specifies the extender only, as the back panel is not included. Check compatibility with existing screw-cover mechanisms on the base unit.

Selection Notes

Select this extender when existing pull box capacity is insufficient for new circuit additions. The galvanized finish suits indoor or protected outdoor environments. Verify that the 4-inch depth meets specific wire bending radius requirements. Ensure the base enclosure supports the structural load of the extension.
