A1-706CT

Overview

The Hoffman A1-706CT is an APO flat transparent screw cover designed for NEMA Type 4X applications. Constructed from fiberglass, it measures 7.32 x 5.94 x 5.50 inches (186 x 151 x 140 mm). The unit features a light gray color and includes four non-metallic corner screws. It serves as a maintenance-free, corrosion-resistant component for insulated electrical junction boxes and terminal wiring enclosures.

Feature Summary

• Transparent design allows visual inspection of internal components without opening the enclosure
• Fiberglass construction provides corrosion resistance and maintenance-free operation
• Includes four non-metallic corner screws for secure attachment

Applications

• Insulated electrical junction boxes
• Terminal wiring boxes
• Instrument enclosures requiring visual monitoring

Procurement Notes

Verify that the specific application requires a transparent cover rather than opaque variants like the A1-706. Confirm dimensional compatibility with the corresponding base enclosure to ensure proper fit. Check for any specific environmental ratings beyond standard NEMA 4X requirements relevant to the installation site.

Selection Notes

Select this model when visual access to internal wiring or components is necessary while maintaining environmental protection. Ensure the base enclosure matches the required dimensions and mounting configuration. Consider the material properties of fiberglass for corrosive environments where metal covers might degrade over time.

Part Context

This part belongs to the Hoffman APO series of fiberglass enclosures. These systems are engineered for harsh industrial environments. The A1-706CT specifically denotes the transparent cover variant, distinct from opaque versions in the same size family.

Replacement Considerations

Direct substitutes include other transparent covers within the APO series if dimensions align. Verify that alternative manufacturers offer equivalent NEMA 4X ratings and fiberglass construction for comparable durability.
