The saucer caddy pro came about as a result of many requests to do a professional grade caddy due to the wide variety of extra large pots now available at the retail level. Our thickest gauge steel, and six extra heavy duty casters, two with locks on them to keep from rolling, hold up to 500-pound. Individually boxed for re-shipping, and inside a master carton of 4 caddies, finished in black. Measures 21-inch diameter.
