This handy pan will save you money by saving your 20kg salt and mineral blocks. The bottom of the pan has inner ribs with square ends that lift the salt block, while the outer bottom rim holds the pan up off the ground so moisture can escape through drain holes. Made of impact-resistant DuraFlex plastic for long wear. Measures 470mm square by 135mm high. Holds a standard 20kg salt block or 10 litres of dry material (will not hold water).
