<p>The barrier has vertical posts (2) on which are fixed traverses (3) parallel to the ground, the traverses in turn carrying infill vertical posts (4). The rigid elongated connector (7) extends through a post so that two traverses can be fixed to each connector, the connector being orientated to take the rectangular longitudinal notch (9) at the end of each traverse. The connector has holes (8) and the traverses have holes aligned to take nuts and bolts (12), while each post has an internal notch (13) in its base that fits over a fixing plate (14) buried in the foundation.</p> |
