Large tool box on wheels for excellent mobility of Qbrick modular systems. Two rubber-covered inrun wheels mounted on a metal axle allow for safe transport of even complex sets. A telescopic, aluminum handle that tilts when the lid is opened, provides comfortable access to the inside of the box. The standard cover (VARIO) in QS ONE Cart is equipped with additional connectors that allow for connecting this version of the cover with the toolbox models from the Qbrick System PRO line (500, Toolcase, Toolbox, Organizer 100,200,300 and alternatively PRO 600). This is a unique version of the box, thanks to which the user can combine elements from two product lines.
