The CSHANDLEKIT Mobile Cart Conversion Kit includes a reversible handle, rolling caster wheels and power cord manager that easily attach to your AC or USB charging station.* Perfect for schools, offices, warehouses, healthcare facilities and other locations where multiple tablets or Chromebooks are used regularly, the CSHANDLEKIT allows for smooth mobility of your charging station. The four rolling casters are non-marking for environments where this is mandatory, and two of the casters lock into place for maximum stability at rest. The casters, easy-grip handle and convenient power cord manager mount to the charging station using the included hardware. The CSHANDLEKIT supports a maximum load capacity of 350 lbs (158.8 kgs).
