Vertiv Isolation Plate 30W X 42D ES CAB - GL-ISO3042

Vertiv GL-ISO3042 Isolation Plate 30W x 42D ES Cabinet

Overview

The GL-ISO3042 is an isolation plate designed for Vertiv Environet Series (ES) cabinets in the 30-inch wide by 42-inch deep footprint. Isolation plates serve a specific structural and thermal function inside rack enclosures: they blank off unused rack sections, compartmentalize airflow between cable management zones and active equipment bays, and prevent bypass air from short-circuiting your cooling path. In data center and network closet deployments where hot-aisle/cold-aisle containment matters, an unsealed panel gap is a measurable efficiency loss — the GL-ISO3042 closes that gap in the correct cabinet geometry without modification or custom cutting.

Compatibility

The GL-ISO3042 is dimensioned specifically for Vertiv Environet ES cabinets with a 30-inch width and 42-inch depth profile. Verify your cabinet's internal width and depth against these figures before ordering — Vertiv's ES line ships in multiple width/depth combinations (24W x 36D, 24W x 48D, 30W x 48D, among others), and isolation plates are not interchangeable across footprints. This plate is not a universal fit for third-party or non-ES Vertiv server rack cabinets.

Installation Notes

Installation drops into the existing ES cabinet rail system — no drilling or permanent modification required in standard configurations. Confirm the mounting rail pitch and panel attachment points match the GL-ISO3042 before deployment in non-standard or field-modified cabinets. For thermal containment to be effective, all adjacent panel positions should also be blanked; a single open 1U gap can undermine an otherwise well-sealed enclosure. Pair with compatible rack accessories and blanking panels across the full cabinet height for best airflow discipline. Consult your data center infrastructure layout plan to confirm isolation plate placement aligns with your hot/cold aisle containment strategy.
