Sturdy-build attachment for 140-qt planetary mixer. 27-3/8" high, 15-3/4" wide, 10-1/8" diameter base. Some dirt appears to have lodged in this item's crevices. Utility-wise, however, this tough aluminum blade should be good for many more runs in the mixer. Here below, this item (left in picture) shown beside an identical piece we're selling (assuming it's still in stock), with less of that built-in dirt.
