Step 1 - Read the instructions fully and lay everything out where it belongs
Remember, you are doing a custom installation that requires alignment with the lines of the truck bed. Think ahead as if you only get one chance to do it right. Mark the location of the holes and rails for future reference.
Figure 1. Lay all the components on the ground.
Step 2 - Connect the rails
It’s a good idea to leave things loose until final adjustment. Follow the manual that came with your tonneau cover, and connect your rails. They will most likely either bolt in pre-drilled holes, or snap on underneath your rail covers.
Step 3 - Install any seals
Following the instructions, install any seals that needs to be installed. Make sure each seal is tight before tightening any bolts.
Step 4 - Install the top
Place the top on and fasten it to the rails. The top should just snap on the rails.
Step 5 - Check and adjust accordingly
Check the seals for potential leaking spots. Adjust the connections for free and easy movement of the top.
