Solid & Smart
All the strength without the limits
1. The roof over your bed
Our panels are crafted from laser welded .080” 5052-H32 solid aluminum, with 50% greater tensile strength than 3003 alloy aluminum.
2. These are no cheap hinges
Hinges machined from 6061-T6 Aircraft Grade Aluminum with Type III UV Resistant Anodizing (architectural grade). In other words, the bees knees.
3. Built to carry
Machined aluminum and architectural anodized tie-down cleats are integrated directly with the structural support stud underneath, ensuring your cargo on top isn't going anywhere.
4. Layers of protection
Your cargo is sealed from the elements by multiple layers of protection, including a full perimeter gasket, secondary rail seal and internal rain gutters at the hinge points.
5. Welded Support Beams
5052-H32 aluminum welded structural support beams provide weight distribution and increased strength.
6. Twice the Finish of other Covers
Literally. First we powdercoat the entire cover with an underbody automotive grade powder to provide incredible adhesion and tooth for the final coat. Then we throw down an indestructible spray-on bedliner finish ready for anything you can throw at it.
30 Minutes or Less
Easy Install
Peragon® Tectonic™ was purposefully designed with easy installation in mind. No professional installer needed. You'll be done in 30 minutes or less.

Bed Cover Reviews
2026 Ford F-150
Instructions were very helpful. I was able to install it myself in about an hour (had to use one of my tools instead of the Allen wrench supplied to adjust rail rollers) and my age is 67. All questions regarding shipment, delivery and installation were promptly and courteously answered by customer service reps. Cover fits my Ford F-150 like a glove. Also, I’ve received multiple compliments from friends on how great it looks. I’m very happy with my choice.

2016 GMC Sierra 2500
I’m thoroughly impressed by the Tectonic cover I purchased for our 2016 GMC Sierra 2500. The build quality is stellar and I have no doubt that it will serve us well for many years. I’m an over analyzer and have put the purchase off for months to make sure it was right and wish I hadn’t hesitated. Installation and the instructions are extremely strait forward and not rushing it took 30 minutes to install. The shipping crate ensured everything got delivered without any damage. Tectonic is heavy duty, but easy to operate and you can see the thought, pride, and detail that went into building such a high quality bed cover. The slots to hold the rail clamps were an awesome touch and you believe in split washers, matching hardware, and torque specs! After an initial adjustment of the rollers, it glides forward and back and seals well. I couldn’t be happier with the purchase and will certainly return to Peragon in the future.

I was pleasantly surprised at how easy the installation was. The tectonic cover is super solid and secure. The day after installation we had 2 days of steady rain and saw no signs of moisture in the truck bed. The only reason for a 99 for customer service is there was one small item missing in the package, however I had an equivalent item so no big deal.

2025 Ford F-150 Raptor
Looks amazing on my raptor. By far the best quality out there. Customer service amazing. Made in America . I have many bed covers and no one can compare to peragon. The higher price point concern went away as soon as I opened up the box. Keep doing what your doing because its perfection. Install was easy. The only thing i would change is the peragon logo location on the tectonic cover. I personally think it would look better centered on the back instead of to the side.
