Review the instruction pages in their entirety to prepare the required tools
Warning: The included J-Bolts must be used during installation to secure the crossover tool box to the truck
bed. Do NOT use self-tapping screws on crossover tool boxes. Self-tapping screws can be used only on chest
style tool boxes being installed to the truck bed.
The tool box warranty is void if one of these securing methods is not used.
Note: Dee Zee tool boxes are NOT air tight. An air-tight seal allows condensation to form inside of the box,
causing the contents to be susceptible to mold or rust. Dee Zee boxes feature various bulb seals and foam
gaskets on the lid to help resist weather elements.
Tool box locks are provided as a theft deterrent and they should always be engaged to prevent easy access to
the contents of your tool box when not in use. Contents stored in the tool box are the responsibility of the
user and Dee Zee disclaims responsibility of theft. Dee Zee does not insure any loss of contents.
Cleaning: To be entitled to all warranty rights offered with the product, Dee Zee tool boxes need to be cleaned
regularly with a mild detergent. Do NOT use abrasive cleaners. For stainless steel products, the application of a
high grade automotive wax is recommended.
