Procurement Notes

Verify compatibility with the specific base enclosure model before purchase. Confirm that the required extension depth of 4 inches meets the spatial constraints of the installation site. Ensure the painted steel finish aligns with existing equipment aesthetics. Check for any specific mounting hardware requirements not included with the extender unit.

Selection Notes

Select this extender only when an existing 30x24 inch enclosure requires increased depth. The Type 1 rating limits usage to indoor, dry environments free from dust, falling objects, and dripping liquids. Consider the total weight capacity of the mounting structure when adding the steel extender. Verify that the screw-cover mechanism remains accessible after installation.
