A51-1912CT

Overview

The A51-1912CT is a flat transparent screw cover manufactured by Hoffman Enclosures, Inc. It is designed for use with NEMA 4X enclosures and is part of the APO series. The component is available in sizes ranging from 7x6 inches (178x152mm) to 24x24 inches (610x610mm). These covers are characterized as maintenance-free and corrosion-resistant, providing a protective barrier while allowing visibility into the enclosure interior.

Feature Summary

• Transparent design allows visual inspection of internal components without opening the enclosure
• Constructed from materials that provide resistance to corrosion
• Designed as a maintenance-free component for long-term durability

Applications

• Covering NEMA 4X industrial enclosures
• Protecting electrical or electronic equipment from environmental contaminants
• Applications requiring visual monitoring of internal status indicators

Procurement Notes

Verify the specific dimensions required for the target enclosure, as the A51 series spans multiple size configurations from 7x6 to 24x24 inches. Confirm compatibility with the base enclosure model before procurement. Ensure the application environment aligns with the corrosion-resistant properties specified for this transparent cover type.

Selection Notes

Select the A51-1912CT when visual access to internal components is necessary alongside protection against harsh environments. This transparent option contrasts with opaque variants like the A51-1912H. Choose based on the exact length and width requirements of the associated Hoffman enclosure base unit to ensure proper fitment.

Part Context

This component belongs to the Hoffman APO series of enclosure accessories. It serves as a replacement or original cover for flat-style enclosures. The product line emphasizes durability and low maintenance for industrial settings where exposure to moisture or corrosive agents is a concern.

Replacement Considerations

The opaque variant A51-1912H is a direct functional substitute if transparency is not required. Verify dimensional compatibility with the existing enclosure base when switching between transparent and opaque models within the same series.
