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've had my cover for over a month now, and I really like how it has expanded my truck's storage capacity. Increasing the covered and/or lockable portion of the truck's storage makes fieldwork more efficient and makes it easier to transport samples. I live in the PNW, so I had hoped for better waterproofing with this product, but I get rain in the bed pretty regularly. I also had issues with the seal above the tailgate lying down properly, and while trying to use tape to help it back into the correct position, I accidentally pulled some of the seal off. This further reduces the seal, so I'll have to come up with a better solution for the coming fall season. It is great to have a less dusty location for flying my drone, and keeping things safe as I travel through various large cities for work. All the guys I work with have asked me about it and are a little jealous, so hopefully I can inspire a few more to be added to our fleet.

I'm very impressed with the Techtonic cover so far! I like the ease of access to the entire bed. Last week it survived about 4+ inches of rain without a leak, and golfball+ sized hail without a mark.
Thanks again! Great product!

Great cover! I was initially concerned after reading some reviews about potential water seal problems, but after experiencing several heavy rains, I haven't encountered any issues. I added extra weather stripping just in case, but it probably wasn't needed. Overall, it looks fantastic on my truck and has garnered lots of compliments. I especially appreciate the tri-fold feature, which allows me to easily adjust the cover on the rails. Installation and usage were straightforward.

Returning client, had a LimitedHDX, wanted more access to the whole truck bed. Installation was under an hour. Best possible upgrade purchase you can buy for your truck. If the price tag is an issue, Peragon has a plan for you. You will not regret this purchase!!!! Hands Down

Love the Tantonic Cover! So far it has been solid. Called the Installation tech to ask about the Tacoma Bed rails that originally came with the truck because they have cut outs. Even though I had to replace them with non-cutout OEM's, the tech I talked to was great.

2025 Ford F-350
After researching several options for my 2025 F-350, I went with the Tectonic Dual-Motion Tri-Fold and overall I’m happy with the decision.
Installation was straightforward with two people and basic hand tools. Nothing about the process was frustrating, and I appreciated that it can be fully removed when needed without much hassle.
Shipping was fast and delivered directly to my door — no freight terminal pickup required, which was a nice convenience.
Build quality feels solid. This thing is built to handle the elements, and I have every reason to think it’ll hold up over the long haul.
My only real gripe is minor — during a particularly heavy rainstorm, I noticed a small amount of water getting through. It’s not enough to cause any concern for cargo, and I suspect it’s within normal tolerance for a folding cover design, but worth noting if you’re expecting a completely watertight seal in extreme conditions.
The price is steep, no question. It’s a premium product at a premium cost. That said, if it lasts the life of the truck — which it appears built to do — the value proposition holds up over time.
If you’re willing to invest upfront and want a cover that installs easily, ships quickly, and is built to last, this is a strong contender.
