This is a set of (12) Sports Training Spring Loaded Agility Poles. Each pole comes ready to use, no assembly required. The bottom of each pole has a stake to secure and stand up your poles in turf, grass or sand. Spring Loaded is for rebound which means they can take a hit and bounce back. These orange and yellow Spring Loaded Agility poles are perfect for setting up your own speed and agility course. (We also sell the bases for hard surface use - sold separately.)
