This all-purpose rebounder is constructed of 1 3/8" OD galvanized steel tubing. It is adjustable to many angle positions. The front frame is concave shaped making the ball accelerate off the net in a less predictable manner. Rebounder includes 2.5mm knotless nylon net with an elastic suspender webbing that makes the ball rebound. Also included are J-shaped ground anchors. This is a great tool for repetitious skill training.
