4.1 Pre-Installation
Before installing the tonneau cover, ensure your truck bed is clean and free of debris. Any existing bed side rails, cargo racks, tool boxes, or headache racks must be removed to ensure proper fitment and function of the tonneau cover.

4.2 Installing Side Rails
- Position the side rails along both sides of the truck bed, ensuring they sit flush and even with the bed rails.
- Loosen the clamp thumb screws and insert the clamps into the rail slots.
- Install all clamps before fully tightening. Once properly aligned, tighten securely.

Note: If the installation hole touches the clamp, please move the clamp so that they cannot come into contact with each other.

- Align the cover with the bulkhead and secure both sides evenly using the integrated front clamps.
- Unroll the cover towards the tailgate, ensuring it is centered.
