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.
