The Beta Tools 5-Drawer Tool Box, No. C23S, can be placed on a workbench or on the top of another tool storage device. There is an external frame that can be seen in the four corners as well as the top and bottom. This design provides a sturdier frame to protect the box from the type of damage that would normally render drawers unusable in sheet metal toolboxes. The hinged lid has storage underneath and the entire unit is key locking. The side handles are hinged so they completely recess into the box and nothing is protruding.
