With the Dewalt DWV9510-XJ rack attachment, you turn your dust extractor into a complete mobile workstation. Instead of carrying loose tool boxes or making repeated trips to your van, you securely mount your Tstak and Toughsystem cases directly on top of your vacuum. This rugged adapter fits all Dewalt DWV9XX dust extractors, including the DWV902 and DWV905. Thanks to the reliable locking design, stacked storage units remain completely stable when rolling across rough jobsite floors. You easily transport your extractor and tools together in a single trip while keeping your work area organized.
