A1284SU

Overview

The Hoffman Enclosures A1284SU is a screw-cover pull box extender designed for Type 1 applications. Constructed from painted steel with a gray finish, it measures 12 inches in length, 8 inches in width, and 4 inches in height. The unit features unique keyhole screw slots to facilitate easy installation and includes plated steel screws for mounting directly to compatible pull boxes. It maintains the integrity of existing Type 1 pull box accessories while providing additional internal volume.

Feature Summary

• Constructed from painted steel with a standard gray finish
• Features unique keyhole screw slots for simplified mounting procedures
• Includes necessary hardware for secure attachment to pull boxes
• Designed to maintain compatibility with standard Type 1 pull box accessories

Applications

• Commercial electrical installations requiring extended wire capacity
• General industrial environments utilizing Type 1 rated enclosures
• Projects replacing custom-sized pull boxes with standardized components

Procurement Notes

Verify that the target pull box dimensions match the required 12x8 inch configuration before procurement. Confirm that the application environment remains within Type 1 rating limitations, as this extender does not provide weatherproof or dust-tight sealing beyond the base enclosure. Ensure adequate clearance exists for the additional 4-inch depth extension during final assembly planning.

Selection Notes

Select this extender when existing pull boxes lack sufficient space for wire pulls but require maintenance of Type 1 classification. It serves as a direct replacement for custom-fabricated extensions, offering standardized dimensions and pre-drilled mounting points. Consider total system depth constraints to ensure the combined height fits within panel or rack specifications without interference.

Part Context

This component belongs to the nVent Hoffman line of general enclosure accessories. It functions specifically as an extension module rather than a standalone enclosure. The product supports standard industrial wiring practices by allowing modular expansion of wire management spaces without compromising the structural or protective characteristics of the primary junction or pull box assembly.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify dimensional compatibility with existing base units before attempting substitution.
