This bit tray is designed to fit in the large bins from the Dewalt TSTAK organizer. They will also fit in the Craftsman Versastack organizer as they are basically the same product only red. Additionally they will also work with the bins from the Dewalt Deep Pro Organizer. They WILL NOT work with the Tough System organizer bins.
The tray accepts the bit holders from the Dewalt ToughCase and ToughCase+ systems. It has the same dovetail system as the ToughCases and the bit holders will slide right in. The tray has approximately the same capacity as a single side of a ToughCase box.
