This double stacking nesting cup fits inside the original supplied cups on the Dewalt TSTAK system and maximises storage space for smaller items like nuts and bolts by creating 3 tiers within each cup.

The divide on the insert cup (smallest of the 2) maintains the seal to the lid when closed, to prevent mixing of contents from one side to the other.

Also compatible with the rebranded storage cases sold by Stanley and Craftsman as per the original design.
