Interior Panel for 12-Gang Layout

This steel interior panel accepts up to twelve component gangs and fits inside 20-inch by 20-inch Concept-style enclosures. It provides a flat mounting surface for switches, outlets or terminal blocks in industrial control builds. The white finish improves visibility during wiring and inspection.

Sustained Load Behaviour

The 12-gauge steel construction resists flex when multiple heavy devices are mounted across all gang positions. Heat from densely packed components dissipates across the full 18.20-inch by 18.20-inch surface area without hot spots. Rigidity remains consistent during continuous vibration from nearby machinery.

Upgrade Context

The panel replaces blank cover plates or thinner gauge sheets that cannot support a full 12-gang layout. The jump is worthwhile when the enclosure must carry a complete row of motor starters or pilot devices. It is not suited for enclosures smaller than 20 by 20 inches or for single-gang retrofit jobs.
