MODbox™ 4-Wheel Caster Dolly with Interlocking Design

The Klein Tools 54828MB MODbox 4-Wheel Caster Dolly is a heavy-duty mobile base designed to transport MODbox stacks and create a mobile workstation on the jobsite. It connects to MODbox boxes with cleats and features side and back latches that allow up to four dollies to interlock for a larger platform.

Best Used For

  • Electrical & Construction Work: Move organized MODbox tool storage between work areas without repeatedly lifting individual boxes.
  • Jobsite Tool Transport: Create a mobile base for MODbox stacks and transport tools and equipment across the jobsite.
  • Workshop & Service Applications: Configure multiple interconnected dollies when additional platform capacity and modular storage mobility are needed.

Key Performance & Safety Features

  • 250-Pound Load Capacity: Each dolly supports up to 250 lb for heavy-duty transport and storage of tools and equipment.
  • Four 4-Inch Wheels: Four wheels provide mobile support for MODbox storage configurations.
  • Interlocking Design: Side and back latches allow up to four dollies to interlock and create a larger platform base.
  • Front-Locking Casters: Two front casters lock to help hold the dolly in position when used as a stationary workstation.
  • Dual Wheel Positions: Inboard wheel positioning supports additional dolly connections, while outboard positioning provides stability when the dolly is used independently.
  • Controlled Loading: A brake pedal helps hold the dolly securely during MODbox mounting for more controlled loading.
