Dell part number 0H4X6X is a 2U sliding ready rail kit designed for Dell PowerEdge R-series rack servers, specifically compatible with R520, R720, R820, and R730 models. This rail assembly enables smooth, tool-free installation and removal of servers from standard 19-inch server racks, supporting the full depth travel required for maintenance access to front and rear components. The kit includes left and right rail channels with ball-bearing slides rated for the weight capacity of supported server models. Typical deployment environments include data centers, server rooms, and colocation facilities where frequent hardware access and serviceability are required. The sliding mechanism reduces installation time and minimizes physical strain during server deployment, upgrades, and decommissioning. Compatible with any standard 4-post or 2-post rack infrastructure. Tested and guaranteed; available via quote.
