Step-by-Step Guide

Choose the Installation Location

Start by selecting the ideal location for your under tray tool box. Consider factors such as accessibility, clearance, and the weight distribution of your tools.

Common placement options include under the truck bed or trailer. However, the exact spot may vary depending on your vehicle's design and your specific needs. Make sure the chosen spot does not interfere with the vehicle's exhaust, suspension, or any other components.

Prepare Your Vehicle

Clean the chosen installation area thoroughly to ensure a secure fit. Remove any dirt, debris, or rust that might interfere with the installation process.

Position the Tool Box

Place the under tray tool box in your chosen location. Use a level to ensure it's perfectly horizontal or sloped as needed (to prevent water buildup).

Using your measuring tape and marker, measure and mark the hole positions for the mounting brackets on the vehicle's undercarriage. Ensure that the marks are accurate and evenly spaced to provide secure support for the tool box.

Drill Mounting Holes

Carefully drill holes in the marked locations. The size of the holes should match the diameter of the mounting hardware provided with the tool box.  It's crucial to use the correct bit size to ensure a snug fit for the mounting hardware. Be cautious and wear safety gear during this step.

Attach Mounting Brackets

Secure the mounting brackets (if included), to the bottom of the toolbox using the provided hardware. Ensure they align with the holes you drilled in the previous step.

Install the Tool Box

Position the tool box back in place, aligning the holes in the mounting brackets with the holes drilled in your vehicle. Insert the provided bolts or screws through the holes and tighten them securely with a wrench or screwdriver.

Final Adjustments

Double-check the level of the tool box and make any necessary adjustments to ensure it's securely mounted and water-tight. Ensure that all mounting hardware is tightened properly.

Test for Security

Give the tool box a gentle shake to make sure it's securely fastened. It should not move or wobble. Test the latches or locks to ensure they function correctly.
