The Super Stacker is the upgraded version of the original Bucket Stacker, and includes all of those features, but is 1-1/2 in. taller to hold a little more. It is a molded plastic small parts organizer tray, in red, designed to stack inside of most 5 gal. buckets. Equipped with four compartments, as well as a molded center handle, you can stack up to three Super Stackers in one 5 gal. bucket, or use them as a mobile small parts tray. The Super Stacker holds not only small parts and tools but also such things as sewing accessories, craft supplies, office supplies and small gadgets. Up to three Super Stackers can be stacked and stored in one 5 gal. bucket.
