Racks Accessories are designed to reduce the amount of time required to properly install Dell components into the Dell rack cabinets. You have to consider the rack accessory type and size of the rack when determining which accessory to select. Sometimes it is also important to know whether the rack is a 2-post or 4-post product. These attributes are listed in the Tech Specs section of this page. We recommend that you use the System Drill Down functionality in the Parts For Your Dell tool to order your Rack Accessory. Please note that some of our replacement products are provided as kits or assemblies. These kits may contain additional parts required for installation; these parts will be listed separately as 'Component Parts' in the Highlights section of this page. In case a product is not sold as a kit or assembly, it may require complementary parts for ease of installation. Please note that this replacement product is refurbished.
