This basin clips onto a standard 10" diameter hanging planter (such as those commonly sold with flowers at garden centers) to catch the overflow from watering and keep it from dripping onto a patio or deck, or anyone passing underneath. Excess water can either be emptied or allowed to soak up through the bottom of the pot as the soil dries.
About 9" in diameter by 3 3/4" deep, it has four fold-out hooks that provide secure support. Made of strong, clear plastic, it is inconspicuous and easily cleaned.
Made in USA.
