1. The tool cabinet/chest combo is a kangaroo. The joey, a detachable smaller tool chest, lets you take your tools beyond the garage or workshop without having to move your tools from the cabinet to a tool box or buy a second set of tools for a portable box. When you're done with a job, joey goes back in the mama cabinet's pouch.
2. For jobs away from your tool cabinet, store a portable or foldout workbench or table in the tool chest combo. Keep the tools you'll most likely need to cart away in the tool cabinet's chest drawers so you won't have to move them around.
3. Kennedy's roller tool chest and cabinet combo comes with a chest or large tool box on top (includes two drawers and an upper tray) for portability and a cabinet with five drawers and wheels for mobility.
