Abstract
Abstract A sectional fence composed of a lattice of bars running horizontally and vertically. The ends of at least some of the bars are formed with connector forms such that one end of the bar can be connected to its opposite end to form a cylindrical fence, such connector forms also being thereby connectible to similar connectors on other sections of fence to build up a larger fence by sections either horizontally or vertically.
