For use with the DWV012 and DWV015 Dust Extractors, the Storage Accessory Rack (DWV016TSRK) is available to interlock with TSTAK and TOUGHSYSTEM storage solutions to provide the user with additional storage, mobility, and durability in jobsite conditions. The optional storage accessory rack screws into the top of your dust extractor to allow vertical stacking of TSTAK and TOUGHSYSTEM boxes. Using the accessory rack allows you to move your tools and dust extractor to and from an on-site location without having to make multiple trips.
