The A31-EXT1207LG is an extension collar manufactured by Hoffman Enclosures, Inc., designed to increase the depth of APO series enclosures. This component measures 11.89 inches in length and is constructed from corrosion-resistant materials to ensure durability in various environments. It serves as a maintenance-free accessory that integrates with existing enclosure systems to provide additional internal volume without requiring complete unit replacement.
Verify compatibility with the specific APO enclosure model before procurement. Confirm that the extension collar matches the required depth increase specifications. Ensure the material composition meets environmental resistance requirements for the installation site. Check official documentation for mounting hardware inclusion or separate purchase needs.
Select this part when additional internal space is required within an APO series enclosure frame. Consider the 11.89-inch dimension impact on overall system footprint. Evaluate if corrosion resistance aligns with the operational environment. Compare against alternative deep-draw enclosures if modification is not preferred.
This component belongs to the Hoffman Enclosures accessory line, specifically engineered for the APO series. It functions as a structural add-on rather than a standalone housing. The product supports modular expansion strategies, allowing users to adapt standard enclosures to non-standard depth requirements through simple assembly.
No public confirmed substitute part numbers are available for this specific extension collar. Verify exact dimensional compatibility with existing APO frames before attempting integration with other manufacturer components.
