Measure Your Truck Bed for a Tonneau Cover

Does your truck have a track system?

The Extang Classic Platinum toolbox tonneau cover is an ideal solution for trucks already equipped with a toolbox, or for future toolbox installs. They are custom fit and will form to most standard 18-20" toolboxes. Get the same great protection as with other Extang truck bed covers, with the advantage of keeping your toolbox.

The Classic Platinum toolbox tonneau features a tail rail which offers a quick release, as well as snaps that are made of indestructible brass. The monster bows and frame are made from anodized aluminum, and give added support to keep the tough vinyl tight in all weather conditions. The vinyl cover has a thick polymer backing and anit-curl corners for a premium fit. The TuffKlamps are a no-drill install and have two modes for adjusting the bows. The HIGH setting is for hotter climates and helps shed maximum water in heavy rain, while the low setting is for colder climates to allow extra slack.

The Classic Platinum toolbox tonneau cover features the patented L-Channel sealing system. This system is made out of anodized aluminum and seals the gap between the tonneau and toolbox. The L-Channel also acts as a rain drainage system, keeping your toolbox and tonneau free of moisture and debris. Extang backs the Classic Platinum with a lifetime warranty on the frame and a 10 year warranty on the cover. Get added security, protection and a sleek design with the Extang Classic Platinum toolbox tonneau cover today!

Order Notes

The cargo management, utili-track, or deck rail system options refer to the factory installed rail system designed to hold moveable cargo cleats along the inside of your truck bed. Please call us for further clarification.

Ease of Installation
I bought this product for my brand new RAM. I did ALOT of research and everything seemed great! I watched installation videos and looked up pictures. Even went to a couple local shops that in stalled bed covers. The quality today isn't like what it used to be. The look is not that bad. And the price is ok I guess, you get what you pay for. But as for the product working, NO. I have tried everything and I always get water in my bed. Not a little but a whole lot. I know no bed cover is 100% water proof. But I honestly expected more from this product. Just really disappointed. I hope the next person that orders this has better luck than I did. And as for the installation took a lot longer then it should have. The clamps that are made for it do not match up right on the rails. Again things that should be fixed b4 a customer buys this. I've worked with RealTruck b4 and there service has been good. Again hopefully the next customer will have better luck and a easier time than I did.
