These specialty tool boxes from Dee Zee use old and trusty padlocks to secure you cargo. A specially designed locking mechanism utilizes any 1" padlock to securely lock the lid to this tool box. This not only makes the lock much harder to defeat, but also allows you to minimize the amount of extra keys to keep track of. To add to the strength and security of the tool box, the Padlock Tool Boxes are constructed from thicker tread-style aluminum than Dee Zee's other tool boxes, making these tool boxes sturdier, stronger, and more secure than most other tool boxes on the market.
