It provides a ventilated surface for mounting or resting equipment within standard EIA rackmount systems. At 3U in height, 19 inches wide, and 18 inches deep, it fits a wide range of rack cabinets used in AV, IT, and low-voltage systems integration. The perforated or vented surface promotes airflow around heat-sensitive components. Installers in data center buildouts, structured wiring closets, and commercial AV rack systems commonly specify this shelf when partial-width component support is needed without blocking the full rack bay.\u003c\/p\u003e\n\u003cp\u003eThe U317 is suited for residential and commercial rack installations where a half-depth or half-width support surface is required. Typical use cases include housing small signal processors, power conditioners, cable management accessories, or other lightweight components in a 3U space. It is compatible with standard 19-inch EIA-310 rack enclosures and open-frame racks. Low-voltage systems integrators, AV installers, and network technicians are the primary trades installing this shelf.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVented surface supports airflow around rack-mounted components\u003c\/li\u003e\n  \u003cli\u003eHalf-shelf design allows flexible component placement in a 3U bay\u003c\/li\u003e\n  \u003cli\u003e19-inch wide mounting footprint fits standard EIA-310 rack rails\u003c\/li\u003e\n  \u003cli\u003e18-inch depth accommodates mid-sized AV and low-voltage equipment\u003c\/li\u003e\n  \u003cli\u003eSold individually as a single unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style rackmount accessory for use in standard 19-inch EIA-310 compliant rack enclosures and open-frame rack systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by low-voltage systems integrators, AV technicians, or network installers working within standard 19-inch rack enclosures. Power down or de-energize any active equipment in the rack before mounting the shelf to avoid contact with live connections. Secure the shelf to rack rails using appropriate rack screws for the rail type, which may include 10-32, 12-24, or M6 thread patterns depending on the enclosure. Verify that combined component weight on the shelf does not exceed the load rating of the rack enclosure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRack Width\u003c\/strong\u003e: 19 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShelf Depth\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRack Units\u003c\/strong\u003e: 3U\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShelf Type\u003c\/strong\u003e: Vented Half Shelf\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity Per Package\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: Middle Atlantic - U.S. - Legrand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: U317\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDDLE ATLANTIC","offers":[{"title":"Default Title","offer_id":51685734220082,"sku":"U317","price":204.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1d06b15cd20b5dbfaf3f6bc2cffea96c.jpg?v=1788218215","url":"https:\/\/voomisupply.com\/products\/middle-atlantic-u317-vented-half-shelf-19-in-3u-rack","provider":"Voomi Supply","version":"1.0","type":"link"}
