The tool boxes are designed so the steel wraps front to back to provide strength in the center and bottom of the box, where you need it
The plastic molded end caps and top help protect the box from daily bumps and abrasions as well as keeping the bottom of the box up off the ground.
Nickel plated, steel draw bolts and a full length steel piano type hinge provide greater strength and security.
Boxes include handy lift out trays for frequentlyused tools.
