Karben Sports SmartKart Multi-Use Gym & Recess Cart is the perfect solution for storing and transporting some of your student's most popular physical education equipment. It accommodates approximately 50 hoops, 60 jump ropes, 20 foam noodles and 25 cones. We also added the ability for the 4 upper posts to adjust in height, making them specific in fit for different lengths of jump ropes and cones. 5 industrial caster wheels (two with locks) are also included. One caster wheel is located in the center where most of the weight put on the SmartKart is focused. Made in the U.S. from U.S. sourced structural grade PVC, Karben offers a full 1 year warranty on parts from date of purchase.
