The A61-EXT2412LG is an extension collar designed for the Hoffman APO series of enclosures. Manufactured by Hoffman Enclosures, Inc., this component is constructed from fiberglass-reinforced polyester (FRP) and finished in light gray. It features specific dimensions of 23.78 inches in length, 11.89 inches in width, and 2.36 inches in height. The primary function of this accessory is to increase the depth of compatible APO enclosure units. The part is classified as a maintenance-free and corrosion-resistant component intended for integration into industrial enclosure systems.
Verify compatibility with the specific APO enclosure model before procurement. Confirm that the required depth extension matches the 2.36-inch specification provided by the manufacturer. Ensure the light gray FRP material meets environmental resistance requirements for the installation site. Cross-reference the base enclosure dimensions to ensure structural fitment of the extension collar.
Select this part only when additional internal depth is required for existing APO series enclosures. Consider the FRP material properties for corrosion resistance in harsh environments. Verify that the light gray finish aligns with aesthetic or identification standards. This component is strictly an additive accessory and does not replace the main enclosure body.
This component belongs to the Hoffman APO series accessory line, specifically categorized as an extension collar. It is designed to modify standard enclosure dimensions rather than serve as a standalone protective housing. The part complements the core APO enclosure range by offering modular depth adjustments for specialized mounting needs.
No public substitute part numbers are documented for this specific extension collar configuration. Compatibility is limited to the designated APO series enclosures specified by the manufacturer.
