Vertiv GL-ISO2448 Isolation Plate 24W x 48D for ES Cabinets

Overview

The Vertiv GL-ISO2448 is an isolation plate sized 24 inches wide by 48 inches deep, designed to mount inside compatible Vertiv ES-series cabinets. Isolation plates serve a specific structural and airflow purpose in rack deployments: they physically separate cabinet zones — typically top and bottom sections, or cable management bays — preventing hot exhaust air from recirculating into equipment intakes. In dense rack environments, uncontrolled recirculation can raise inlet temperatures 5–10°C above room ambient, directly impacting equipment thermals and warranty conditions. Installing the GL-ISO2448 creates a hard air barrier at the 24×48 plane, enforcing the thermal separation your cooling infrastructure was designed around.

Compatibility

The GL-ISO2448 is designed for Vertiv ES-series cabinets with a 24-inch width and 48-inch depth footprint. Confirm your cabinet's internal depth against the 48-inch dimension before ordering — ES cabinets ship in multiple depth configurations, and an isolation plate must match the internal usable depth exactly to seat flush and seal the air gap. This plate is not a universal fit; do not specify it for Vertiv cabinets outside the ES line or for third-party enclosures without verifying dimensional compatibility against the cabinet's internal cross-section.
