Two Pack Green Color Plastic Planter Caddies or Dolly for Use Indoors or Outdoors. Four Wheels, Capacity 15 lbs. Each. Measures 13 ¾ inches Diameter and 3 ½ inches high with Extra-high Lip

This product was a real disappointment!! The casters are made totally of plastic. As a result if you have a pot of medium weight or greater you need to take remove the pot prior to moving the Caddy. I purchased four and each has had a caster break if I rolled it over an uneven surface. I was able to repair them by replacing the broken caster stem with a metal 4" screw. This product should be reengineered to inclued a metal stem!!!
