(opens in a new tab)The 2U Rail Kit is compatible with the Generation 14 2U Dell PowerEdge 840 Server and serve as an alternative to Dell RapidRails. RackSolutions rail kits are constructed from high-quality zinc plated cold-rolled steel to support the weight of your 2U servers. This rail kit features a dry slide, which unlike ball bearing slides will last much long longer. Ball bearings often fall out of the rail kit and get lost and can quickly wear over time. Unlike the Dell OEM Rail Kit, RackSolutions rail kit rack mounts in both 2-Post and 4-Post racks as long as they are 19" EIA server racks. The rail kit also works with threaded, round, and universal square holes. In 4-Post Racks, the mounting depth is adjustable from 3" - 30" (76.2 - 762 mm) and in 2 post the mounting depth is 3 - 6" (76.2 - 152.4 mm). A flush mount kit (opens in a new tab)is required for flush mount rail installation. The conversion brackets must match the corresponding rail’s U height (e.g., 1U rail = 1U Conversion Bracket).
