We designed these bolt-on shelves to fit our Leonard 4-Wheeled Flatbed Carts with 24-Inch by 60-Inch Decks. This kit includes a heavy-duty, 11-gauge steel deck and four legs. We include 7-gauge mounting plates and 3/8-inch carriage bolts for mounting. Choose your desired shelf height below. These shelving kits double the carrying capacity of your Leonard 4-Wheeled Cart. These carts are perfect for moving flats, potted shrubs, or bagged materials. The extra storage space makes them ideal garden centers or nurseries. Diamond-shaped drainage holes in the deck prevent water from pooling on the shelf. We engineer these shelves to last! We apply an orange powder-coat to the heavy-gauge steel decks. This coat protects the shelves from rust and corrosion. We back these products with our lifetime warranty! Do you have one of our smaller carts?
