Product Overview The Middle Atlantic MPR-BL4A is a 4-inch blank cover module for the MPR Series Modular Power Raceway System. It fills unused 4-inch module positions in MPR raceway enclosures, maintaining a clean finished appearance and protecting internal wiring where power or accessory modules are not installed. Product Description The MPR-BL4A is a 4-inch blank cover module for Middle Atlantic's MPR (Modular Power Raceway) system. The modular design of the MPR enclosure allows power strips, USB chargers, data port modules, and other accessories to be installed in a fixed-length enclosure. When a module slot is not populated with an active module, blank covers such as the MPR-BL4A fill the gap. The 4-inch length makes the MPR-BL4A suited to filling smaller gaps between active modules, or for configurations where only a short span of the enclosure is unused. Available in multiple lengths (2-inch MPR-BL2A, 4-inch MPR-BL4A, 8-inch MPR-BL8A) to accommodate different gap sizes within an MPR installation. Key Features 4-Inch Module Length — Covers a 4-inch section of unused MPR raceway slot. MPR Series Compatible — Designed for the Modular Power Raceway system. Blank Cover Function — Protects internal wiring and presents a finished appearance at unused slots. Multiple Sizes Available — Available in 2", 4", and 8" lengths to match gap size.
