Middle Atlantic Single Blanking Plate-alu - 430AL

Middle Atlantic 430AL Single Blanking Plate — Aluminum

Overview

The Middle Atlantic 430AL is a single-unit aluminum blanking plate designed to fill unused rack unit openings in equipment enclosures and open-frame racks. When a rack bay has an unfilled opening, airflow bypasses your cooling path — hot air recirculates into intake zones and thermal performance drops across every active component in the rack. The 430AL eliminates that gap with a flush, aluminum-finish panel. TAA-compliant by specification, making it a straightforward choice for government and federally funded installations where sourcing compliance is a procurement requirement. If you are building out a Middle Atlantic rack system and need to manage unused space systematically, the 430AL fits the standard 1U opening without modification.

Compatibility

Designed for use with Middle Atlantic's rack enclosures and open-frame rack systems that accept standard 19-inch rack accessories. The 430AL occupies a single rack unit (1U) position. It is appropriate for any rack accessory build-out where a 1U aluminum-finish blank is needed — including Middle Atlantic's ERK, PD, and similar enclosure families that use standard EIA rack spacing. Confirm your open rack unit count before ordering; for multi-unit gaps, multiple 430AL blanks or a wider blanking panel from the Middle Atlantic line may be required.

Installation Notes

Tool requirements and torque specifications are not published in available documentation. Installation follows standard rack blank practice: align to the 1U opening, seat the mounting tabs or screw holes against the rack rail, and secure with rack screws appropriate for your enclosure rail type. No wiring or cabling is involved. The aluminum finish matches Middle Atlantic's standard enclosure palette — verify finish compatibility if mixing with powder-coated rack furniture in color-sensitive deployments.
