Middle Atlantic HR-EVT1 1U Half-Rack Vent Panel
Overview
The Middle Atlantic HR-EVT1 is a 1U flanged vent panel designed to fill unused rack space while allowing passive airflow through enclosed half-rack and full-rack enclosures. At 10.4 in. wide and just 0.51 in. deep, the HR-EVT1 drops into a single rack unit without consuming meaningful enclosure depth — important when rear cable clearance is already tight. The 17% open area is enough to break up stagnant air pockets between components without the panel becoming a structural weak point. This is the right panel when you need a lightweight filler that still contributes to thermal management rather than a blank that seals the bay entirely. Made from steel with a flat black powder coat finish, it matches standard Middle Atlantic rack hardware aesthetics and finishes.
Compatibility
Designed for half-rack and full-rack enclosures accepting standard 10-inch-wide panels — primarily Middle Atlantic's HR-series half-rack frames and compatible 10 in. equipment rails. Verify your enclosure accepts 10.4 in. panel width before ordering; standard 19 in. full-rack frames require a different panel width. At 1 RU tall (1.75 in.), this slots into any single-unit open bay in a rack cabinet or open-frame rack using Middle Atlantic's flanged-panel mounting standard. If you're managing thermals across a multi-unit stack, pairing this with a rack cooling solution delivers better results than vented panels alone for high-density deployments.
