CPI four-post racks offer the strength and stability of a cabinet in an open architecture. Four-post racks provide easy access to cabling and equipment and unrestricted airflow for ventilation. They also permit the addition of a wide variety of CPI vertical cabling sections. CPI manufactures two styles of fixed four-post frames and two styles of adjustable depth frames to best meet your mounting requirements.
