Angle adjustment is what makes this frame do two jobs. Set flat it is a 6.1-foot goal for shooting practice with friends; tilt the frame to any of its 5 positions between 90 and 57 degrees and the 31.5-by-16-inch middle net returns the ball at a different height each time, so a player can train first touch and volleys alone. Both nets are PE, chosen for strength and the elasticity that gives a quick rebound, and they hold up through wet weather and repeated shots. Galvanized metal pipes make up the frame and the whole thing weighs 17 pounds, light enough to move across a lawn but not so light that it skips backwards on a hard strike. It is aimed at players aged 6 and above.
