Safety Information
Always prioritize safety during installation and use of the Slimpro Van Rack. Failure to follow these guidelines may result in property damage, injury, or death.
- Ensure all components are securely fastened according to the installation instructions. Regularly check all bolts and connections for tightness, especially after initial installation and before long trips.

- Distribute cargo evenly across the rack to maintain vehicle stability. Secure all items firmly to prevent shifting during transit.
- Be aware of increased vehicle height and potential changes in handling when the rack is loaded. Exercise caution when driving under low clearances or in windy conditions.
