Middle Atlantic Blank Panel 1/3 RU Steel Flanged - EB1/3

Middle Atlantic EB1/3 1/3 RU Steel Flanged Blank Rack Panel

Overview

The Middle Atlantic EB1/3 is a 1/3 RU flanged blank panel designed to close unused rack space in 19-inch EIA-standard enclosures. At 0.58 in tall and 19 in wide, the EB1/3 fills the fractional gaps that accumulate between 1U and 2U components — the kind of open slots that disrupt airflow management and leave cable pathways exposed in finished rack builds. Steel construction with a flat black powder coat finish matches standard rack aesthetics and holds up to repeated installs and removals without deforming. Two mounting points secure the panel with a flanged style that seats flush against the rack rail without requiring a cage nut — a minor detail that matters when you're closing out a rack under deadline. This is a single-panel package (Package Count: 1), so order quantity to match the number of open slots in your build. Common deployment scenarios include NVR and server rack builds where partial-RU gaps between appliances need to be sealed, and AV equipment racks in security operations centers where a clean, finished appearance is required.

Compatibility

Fits any EIA-standard 19-inch rack with standard rail spacing, including Middle Atlantic's own rack enclosures, open-frame racks, and wall-mount enclosures. The flanged mounting style is compatible with rails that accept direct screw attachment — verify your rail accepts the flanged style before ordering if your rack uses a toolless or specialty rail system. At 1/3 RU, this panel pairs with other fractional panels (1/3 RU and 2/3 RU) to fill a full 1U opening when mixed-height gaps are present. Works alongside rack management accessories including 1U and 2U blanks from the same Middle Atlantic panel line. For full Middle Atlantic rack accessories, additional fractional and full-RU blank panels are available in the same flat black finish.
