Note: When placing the seal, make sure it’s lined up straight.

Rails 

Rails are an essential part of the accessories. Without rails, you can not install the tonneau cover. When you order or purchase a tonneau cover, it has two rails. One is called the driver seat bed rail, and the other is the passenger seat bed rail.

On the backside of the rails are a bunch of little strips of tape for their proper adhering. Moreover, it assures you that the rails do not come off. 

When installing the rails, I always ensure they sit correctly. I attached the back side of the rail first and then the front side. Pulled the rail tightly so it laid down properly.

Tonneau Cover Clamps 

Clamps are installed to secure the side rails on the truck. The clamps come out of the package preassembled. Engaging the teeth of the clamp with the grooves of the rails is important. 

How I placed clamps on my bed rail, l positioned the clamp into the spaces. The nut faces me. I tightened the clamp with the help of a wrench for a snug fit. No drilling is required. Clamps help in laying the rail flat.

Water drainage hoses drain the water from the rails when it rains. All you need to do is drill the hole at the front part of the truck and run one end of the pipe inside the grommet area. The hose part is right up on the cover. Drain tubes make sure that the water exits the proper way. 

LED Lights 

I was having an issue, especially at night, because I could not find the specific item I wanted. So I decided to install LED lights. LED lights give you bright light anywhere you want. They are portable, and you can quickly move them to where you need to find your cargo. 

You can not move some fixed LED lights. All you need to do is peel and stick the light inside the truck bed without wiring. The ACCESS waterproof 18″ LED light sticks anywhere with tough 3M adhesive and runs on three AA batteries. 

Side Rails

Side rails are installed over the tonneau cover. They provide extra space to add the cargo and are easy to handle. These are specifically designed to complement the angles of the truck.
