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.

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.

It truly was easy to install. Super durable and really exceeded my expectations when it comes to quality. It’s certainly not the cheapest and there’s a reason for that, this thing is amazing. It seals really well and my cargo stays dry. I also love that I can lock up my tools without any hesitations.

I have been buying Bak Covers for years and the last few years have been very disappointed in service and quality of the product , with that being said started looking for a better cover and also one that gives me full access to my bed. All I can say is wow this is like night and day from packaging, ease of installation and quality of material and build. It was harder to unbox then it was to install. The build is strong and great looking. Was a little Leary of spending that kind of money but in the end was well worth the investment. I would highly recommend this to anyone .

Shipment Packaging was very effective and easy to unpack. Installation was a snap. Love that it seals very tightly and securely, you can pack items on top of, you can easy fold it up and push the stack forward or rear, or if need be, you can very easily remove the panels. Seems very durable.

Awesome cover. For my work it offers quick and easy access to the front of the truck bed. The sliding cover is what I have always needed and I have had several different covers.
Install is easy and the video is great.
Customer service in Shell Lake WI was excellent. I had misplaced the key cover supplied. I called and they shipped me another.
I would highly recommend!!

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.
