- Attach the side rails to the canister using the provided shorter screws. Ensure the offset brackets are positioned towards the front of the bed.
- Clamp the rails onto the bed using the hardware kit, aligning with the BoxLink system.
- Ensure the rails are parallel and equidistant from the canister to the tailgate. Use a measuring tool to confirm symmetry.
5.3. Electrical Connection for OEM Key Fob
To enable operation with your factory key fob, connect the yellow signal wire:

7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your tonneau cover.
- Cleaning: Clean the cover surface with mild soap and water. Avoid abrasive cleaners or harsh chemicals that could damage the matte black powder-coated aluminum finish.
- Drainage System: The cover features an integrated water management system. Periodically check the drainage tubes for any blockages from debris and ensure they are clear to prevent water accumulation in the truck bed.
- Rail Inspection: Inspect the rails for any debris or obstructions that might hinder smooth operation. Keep the rails clean.
- Electrical Connections: Periodically check all electrical connections for corrosion or looseness.
8. Troubleshooting
Refer to the following common issues and their solutions:
| Issue | Possible Cause | Solution |
|---|---|---|
| Cover stops short or does not open/close fully. | Temporary power loss or calibration issue. | After power is restored, the cover may require a short period of normal operation (driving) to recalibrate. If the issue persists, manually extend and retract the cover fully. |
| Tailgate does not close properly with the cover installed. | Incorrect adjustment of rear brackets or cover position. | Loosen the bolts on the adjustable brackets (do not remove). Push the canister as far forward as possible. Adjust the rear brackets slightly upward to provide additional clearance for the tailgate. Tighten all bolts securely. |
| Cover operation is not smooth or binds. | Rails are not parallel or debris in the tracks. | Ensure the rails are clean and free of obstructions. Verify that the distance between the rails at the front (canister) and rear (tailgate) is identical to maintain parallelism. Refer to the video below for guidance. |
