Enclosure Backplates

Enclosure backplates provide a secure and organized mounting surface for electrical components while preserving the integrity and environmental rating of the enclosure. Offset from the rear wall of the cabinet, backplates allow devices such as terminal blocks, power supplies, and control components to be installed without drilling into the enclosure body, helping maintain NEMA and IP ratings. RSP Supply carries a wide range of full and half height enclosure backplates manufactured from steel, aluminum, fiberglass, composite materials, and other specialized substrates. Many backplates are pre-drilled to align with enclosure mounting points, simplifying installation and ensuring proper fit. Removable designs allow components to be assembled, modified, or serviced outside the enclosure, reducing downtime and improving accessibility during maintenance.
Material selection varies by application. Steel and stainless steel backplates offer strength and durability for industrial environments, while aluminum provides a lightweight, corrosion-resistant option. Fiberglass, composite, and phenolic backplates deliver excellent chemical resistance and electrical insulation, making them suitable for harsh or corrosive conditions. Half-height and adjustable mounting options offer added flexibility for custom layouts and space optimization.
