Abstract
Systems, methods and apparatus are provided through which, in some embodiments, an extending column is comprised of a plurality of stacked slides that are mounted to each other through linear bearing assemblies that allow the extending column to telescope inward and outward. Some embodiments of the extending column have a synchronization mechanism between each slide to extend each slide in equal distances relative to each other.
