System provides a complete solution for any teacher, both in direction and storage. To determine which length rope to choose, students simply match the height of their sternum to the corresponding color bar on the end post of the cart. Once they know their color, students can "quick select" the right rope every time! Cart is also color-coded for returning the ropes, making selecting, organizing, and storing ropes quick and easy! Cart has 8 color-coded storage rungs (with capacity for hundreds of ropes), tubular-steel construction, and smooth-rolling 2-1/2" dia ball-bearing casters; assembly required (38"L x 21"W x 78"H). System includes the cart with 2 storage containers and 6 Green (6'L), 12 Red (7'L), 18 Yellow (8'L), 12 Blue (9'L), 6 Orange (10'L), and 6 Purple (16'L) QuikSelect™ jump ropes (1/4" dia plastic with 5"L handles); 26 lb total.
