• Measuring tape
• Utility knife
• Power drill
• Drill bits

Step 2: Installing Cover Side Rails

The next step is to install the hard tonneau cover side rails. These rails are the tracks that securely hold the tonneau cover in place on the sides of your truck bed. It involves these steps for installation: 

1. Put the side rail on top of the truck bed’s side. 
2. Keep pushing the rail forward until it touches the front end of the bed. The key is to ensure the rail is tightly pushed against the cab at this end. 

 3. You want to ensure the rail sets flat and level with the truck bed. 

 4. Keep the rail straight and attach the first clamp on the front. Use a wrench to tighten it. 

 5. Once the rail is stable, attach the second clamp in the middle and tighten it. 

 6. Then, install the third clamp at the end near the tailgate. 

 7. Once the rail is installed on one side, repeat this process to install the rail on the other side of the truck bed. 

Step 3: Apply Front Header Seal

Next, moving on to applying the front header seal. Follow these steps for a smooth application:

1. Grab some rubbing alcohol and clean the front edge of the truck bed near the cab window. Make sure there is no dirt and that the surface is clean and nice.
2. Take the front header seal and peel off the adhesive backing from it. 
3. Then, carefully put the seal on the front edge of the truck bed, starting from one side to the opposite end. Keep pressing the seal to ensure tightness. 
4. Once it reaches the opposite end, cut the extra seal with a utility knife.

Step 4: Assemble the Tension Adjusters to the Tonneau Cover 

Now, let’s assemble the tension adjusters to the tonneau cover. Here are the steps:

1. Place the tonneau cover on a flat and clean surface with the front bar facing upwards. 
2. Locate the holes on the cover where tension adjusters will be attached. These holes are mostly on the corners of the cover. 
3. Then, take a tension adjuster and align it to the designated holes. 

          4. Insert the screws through the holes in the tension adjuster. 

          5. Tighten up the screws using a screwdriver.

 

       6. Repeat these steps for all other tension adjusters. 

Step 5: Placing & Securing the Cover on Rails

It’s time to place and secure the tonneau cover on the side rails. Follow these steps: 

1. Place the rolled-up tonneau cover on the top of the rails near the cab of your truck.
2. Adjust and align the cover so that it evenly sits on the rails. 
3. Before securing the bed cover, unfold it all the way to the tailgate to check if it's in the correct location. Once checked, fold the cover up again. 
4. Slide the cover into the side rails. 
5. Match the bolt holes on the tonneau cover with the holes on the rails. Then, tighten these securely, and they will be locked. 
6. Repeat the process for other side holes to have a secure cover installation.

Let’s test the cover and make initial adjustments to ensure smooth functionality. 

1. If the cover is too tight or loose, adjust the tension adjusters. 
2. Then, close the tailgate and see whether it fits properly under the cover bar. 
3. Ensure that it locks properly when closed. 

Step 7: Tightening and Securing the Clamps

Once it is ensured that the tonneau cover is installed correctly, tighten all the clamps to secure everything. 

1. Check the clamps installed on the side rails if they need further tightening. 
2. Use a wrench to tighten up the clamps. Don’t overtighten any of these. 
3. If any other clamps or bolts feel loose, reposition these and tighten them again.  

Step 8: Weatherproofing & Drainage Setup

Let’s learn how to set up the drainage system to protect your truck. 

1. At the very front of the cab, you'll see a little knob on the rails. 
2. Attach the drain tube with this end, and it will hang there. 
3. Route the drain tube to the factory hole in the truck.  

Step 9: Final Inspection and Testing

Finally, let’s do the final test to ensure every latch latches. 

1. Fold and unfold the tonneau cover multiple times to ensure smooth functionality. 
2. Check that all clamps and bolts are tightened securely. 
3. Check for any gaps in the drainage setup.
