The Hoffman Enclosures Inc. model 89112090SP is an assembly cover designed for NEMA 21 series enclosure systems. Constructed from 316 stainless steel, this component provides a durable protective interface for industrial applications requiring corrosion resistance. The unit is supplied in a single-item configuration and is intended to integrate with compatible Hoffman enclosure frameworks to maintain environmental sealing standards.
Verify the specific compatibility of the 89112090SP assembly cover with your existing NEMA 21 series enclosure models before purchase. Confirm material specifications match project requirements for 316 stainless steel construction. Ensure the single-unit packaging aligns with installation needs. Cross-reference official Hoffman documentation to validate fitment details.
Select this component when upgrading or maintaining NEMA 21 series enclosures that require high-grade corrosion resistance. The 316 stainless steel composition makes it suitable for harsh environments where standard materials may degrade. Ensure the physical dimensions of the cover match the target enclosure frame to guarantee proper alignment and secure mounting during assembly.
This part belongs to the Hoffman Enclosures product line focused on electrical housing solutions. It serves as a specialized accessory rather than a standalone enclosure. The component supports the structural integrity and environmental protection of larger assembly systems within the manufacturer's catalog.
No public substitute part numbers are documented for this specific assembly cover.
