Modular 1U Blanking Panel 10 Pack

These black APC blanking panels fill unused 1U bays in any 19-inch EIA-310-D compliant rack. Each panel measures 1.7 inches high, 19 inches wide and 0.1 inches deep. The ten-piece set is designed for quick, toolless installation in square-hole mounting rails. They improve cooling efficiency by preventing hot-air recirculation inside the enclosure.

Suits square-hole racks needing airflow management

Ideal for data-centre operators and server-room technicians who must maintain front-to-back airflow discipline in standard 19-inch cabinets. The toolless clips allow rapid deployment during rack builds or reconfigurations. Not suitable for threaded-hole rails or racks that do not follow the EIA-310-D square-hole pattern. Buyers needing solid metal panels or panels with cable pass-throughs should look elsewhere.

Check rail type and available 1U spaces

Verify that your rack uses EIA-310-D compliant square-hole mounting rails before ordering. Count the number of empty 1U slots you intend to cover so the ten-panel quantity matches the project. Ensure the 0.1-inch depth clearance does not interfere with front-door latches or cable-management fingers. No tools are required for fitting.

Questions about this item

Does the AR8136BLK need square-hole rails on my rack to snap in?

Yes, the panels mount only in EIA-310-D compliant square hole mounting rails; round-hole or threaded rails will not work.

Will these 1U blanks leave gaps that let hot air recirculate around my older 2U servers?

Each 1.7" high panel fills a full 1U space, so stacking them above or below 2U gear closes the openings and stops recirculation.

How can I confirm the ten panels are seated correctly after installation?

Every panel should sit flush with the rack face, show no visible gaps, and resist a gentle pull — if any panel moves, re-seat its toolless clips.
