<p>A continuously height-adjustable jump cup attachment bracket (10) for a sporting fence to support a rail (R) includes a jump cup (42) carried on a bearing plate (40) that frictionally engages a support post (20) provided with a channel (24) and a clamping means (46,48,50,52) associated with the bearing plate (40). The clamping means (46,48,50,52) may be selectively engaged to set the height of the rail (R) of the fence and also to be displaced from such setting in the event of accidental downward movement of the rail (R) in relation to the post (20).</p> |
