Nest & Stack Totes (NSTs) by Akro-Mils are great for storage, transfer and shipping applications. NSTs can be stacked with or without lids for dense storage and shipping. Save valuable space and nest them inside each other when empty. Their strong, high-density, industrial-grade polymers will not rust, corrode or bend out of shape even when fully loaded. Akro-Mils quality, heavy-duty construction provides a longer service life resulting in lower replacement costs than other brands. Nest and Stack Totes will stack when full. Simply turn them 180 degrees to nest when empty.
