A81-2212CT

Overview

The Hoffman A81-2212CT is a flat transparent screw cover designed for APO enclosures. It features Type 4X protection and measures 21.97 x 11.89 x 6.93 inches. Constructed from fiberglass, the component is finished in light gray. The transparent design allows for visual inspection of internal components while maintaining environmental sealing. This cover utilizes four corner screws for secure attachment to compatible enclosure bases.

Feature Summary

• Transparent construction enables visual monitoring of internal wiring and connections without removing the cover.
• Type 4X rating provides protection against corrosion, water, and dust ingress.
• Fiberglass material offers durability and resistance to harsh industrial environments.

Applications

• Insulated electrical junction boxes
• Terminal wiring boxes
• Industrial control panels requiring visual access

Procurement Notes

Verify that the target enclosure base matches the APO series dimensions and mounting hole pattern. Confirm the requirement for a transparent cover versus opaque alternatives. Ensure the installation environment meets Type 4X standards. Check compatibility with existing fasteners and gasket materials.

Selection Notes

Select this model when visual inspection capability is required alongside robust environmental protection. The transparent variant differs from the opaque E2 version by allowing visibility. Consider the specific dimensional requirements of the 21.97 x 11.89 inch footprint. Evaluate if the fiberglass composition suits the chemical exposure levels of the application site.

Part Context

This component belongs to the Hoffman APO line of insulated enclosure accessories. It serves as a replacement or new installation cover for rectangular junction boxes. The product is manufactured by nVent Hoffman, specializing in industrial enclosure solutions. It complements the APO base units to form complete sealed systems.

Replacement Considerations

The opaque equivalent part number is A81-2212E2. Verify that the functional requirement does not strictly demand transparency before substituting with the opaque version. Both share identical dimensions and mounting configurations.
