Procurement Notes

Verify that the required depth adjustment range aligns with your specific equipment footprint before ordering. Confirm that the 2400 lb load rating meets the weight requirements of all installed components. Ensure the 45U height accommodates the total vertical space needed for your server or switch units. Check that the white powder-coated finish is suitable for the environmental conditions of the installation site.

Selection Notes

Select this model when high accessibility and robust load-bearing capacity are prioritized over enclosed protection. The adjustable depth allows for optimization of airflow and cable management within confined spaces. Consider the 4-post configuration for standard 19-inch equipment compatibility. This frame is suitable for environments where thermal management benefits from open-air exposure.
