School Smart stepping buckets help develop balance and coordination skills. Six non-skid buckets are connected by a braided nylon rope for creating an 11.0’obstacle course, and are in bright primary colors for visual appeal—two each of red, blue, and yellow. Nylon is very strong and flexible, has excellent abrasion resistance, is lightweight, and resists crushing and cracking. The buckets are made of molded plastic for durability and strength, and have 1/16″/.20cm raised gripping lines on top for added stability. The buckets measure 5.0 x 12.0 inches/12.7 x 30.5cm (H x W), and can support up to 330.0 lb./149.7kg. (H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right.) The stepping buckets nest for storage, and weigh 7.0 lbs./3.2kg when stacked together.
