<p>A palisade or fence comprises vertical pales (9), rails (7,8) parallel with the ground surface and posts (6) set in the ground, each stretch between posts constituting a panel. The palisade is assembled without welding any part and follows the ground contour by means of its panels adjusting in pivoting fashion from rectangular shapes to parallelogram shapes at inclines or declines. This is facilitated by the pales pivoting on singular pivot formations in apertures in the rails that have clearances or tapers and the rails having pivotal or hinged connection to the posts.</p> |
