Rack Mount Shelf
Server Rack Shelves, Relay Rack Shelves

Which server rack shelf would work best in my server rack? The general rule of thumb is to measure 6" shorter than depth of a server rack for all 4-post cabinets. This measurement will compute the optimal shelf depth for your particular cabinet enclosure. Also, please take into consideration that rails are often set at a distance less then the actual depth of the internal dimension.
