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.

Extremely easy install, all metal pieces that will last, unlike many toppers I've installed in the past. Just due to design, will be the best at keeping water out of the bed naturally. Very impressed!!!

Very high quality cover. I replaced a more common type of folding cover after the structural rubber seals/hinges disintegrated between panels due to UV exposure and being flexed every time the cover is opened. This cover fixes that issue using external hinges in combination with static seals. The last cover was 1000 dollars and ended up in the landfill after 4 years. This cost more money but it will last the life of the truck, no doubt. This cover is also much easier to remove for full bed access. Very satisfied with the purchase.

I purchased the Tectonic bed cover. Unfortunately it did not work with my below the rail bed tool box so I had to return it. The team at Peregon was FANTASTIC.

Love it so far! Makes my '26 F250 Super Duty look badass and super rugged!! Took me 20 minutes to install. I've never seen one in person in my area so I get tons of "whoa, that's sweet!"

This is the best cover I have ever purchased. Very expensive but worth every penny. It is completely waterproof and very secure. I get a lot of compliments on the look. Very rugged. I love this cover and it’s been on the truck for 2 months. Now the customer service part of this. It took 6 weeks to get. When I got it fedex destroyed it. Looks like a fork lift went through the box and bent all the pieces. I called customer service that day and got the nicest lady. I was not happy and not easy to deal with which I feel bad now. That was on Thursday and on Monday I had a new cover delivered. This is my second paragon cover and would buy again.

I called to order because I needed to make sure I could get the cover in time for a roadtrip. Sales rep was super friendly and the cover arrived ahead of the promised time. The cover itself is beautifully made and was easy to install. It was solid under light rain but the desert dust easily found its way into the bed. Maybe this was the tailgate? My one real issue is that I need to unlock both front and back locks every time I want to open the cover to reach deeper into the bed. It would have been great if there was some way to lock and unlock with the tail gate itself.

So far I’m completely happy with the cover.
Installation was a breeze. It only took about 20-30 minutes.
It seems like it’s secure.
Glad I went with this cover.
I also like the Lifetime warranty.
