- Rubber lock caps keep locks free from rain and ice

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.

2026 Ford F-150
Have had it a week now, and its awesome! Installation was a breeze, functions exactly as advertised! Really happy. The real test will come to see how well it handles the sun and heat. But I'm expecting nothing short of "excellent"!

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.

Installation was very easy and directions were helpful and easy to follow. I have climbed on it a few times to get access to thinks high up and it is very sturdy. I love being able to slide the cover where I need it for access.

The Tectonic bed cover is great. Strong, easy to install, operates smoothly, fits perfectly, provides excellent protection from the weather, and keeps things in the bed securely locked away from theft. It also looks better on the truck than I expected. It shipped quickly, and was everything it was advertised to be. I am very happy with it.

I love the three panel design and the fact that it will slide forward and backward. That was my main reason for purchasing. Easy access to the bed and gear. Quick to install. Very happy with my decision. Also love that you can carry loads on top if needed.
