A column grip that supports objects by friction grip to smooth surfaces, particularly columns on a railing system. The column grip comprises a cam assembly that actuates about a main axis to fit between columns located on deck, stairway or hallway railing. A compression spring provides a driving force to secure outer surfaces of the invention against the columns. When supporting heavy objects, its parrot beak design provides mechanical advantage proportionate to an objects weight, by pushing its outer surfaces harder against opposing columns and creating additional friction against opposing columns. A broad range of accessories, including a shelf, hook, gardening accessories, deck light, light sources, decoration, flag holder, and the like attaches to the embodiment. For example, a deck light attached to this invention that not only improve the aesthetic appeal of a deck, but also illuminates its surrounding area and enhance safety.
