Its sturdy 21" diameter base is made of heavy-gauge, powder-coated steel that allows use indoors and outdoors. Six heavy-duty casters roll easily across brick, pavers, or decks outdoors and smooth floors indoors, allowing prized specimens to be spun for easier pruning and watering or moved to different spaces; two casters lock to keep the caddy in place. An included plastic saucer snaps into the base and includes built-in wells that collect water draining from a pot, keeping decks, patios, and floors tidy. Supports up to 500 lbs.
