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.

The attention to detail is evident from product to installation instructions, including videos and even the packaging. Install was very smooth at about 30 mins. Had a very hard rain and inside bed was dry 👍

I debated getting the Tectonic because of the price. I received it about a week and half sooner than expected!! The installation was as easy as shown in the installation video. The cover is awesome. I like that it mounts above the rails and doesn't take up bed space and it's easy to fold and slide. I've got it on an F-350 - 6'9" bed. I know there are cheaper options but having the ability to load and tie down on top was a selling point for me. I have no regrets and would recommend it to anyone looking for a cover!

I have a Tectonic model, and I like the ease of installation and removal if needed. I also have a 50 gallon auxiliary fuel tank in my bed, and this was one of the few covers that would still work with my fuel tank.

Excellent product! A bit pricey, but you get what you pay for in this world. Well secured, sturdy, I was able to mount my newly purchased 50 gallon water heater water heater on top with no problems. The straps worked wonderfully very easy to use. Paragon seems to have thought of everything to include seals around the unit preventing water seepage during car washing nicely concealed cover covers for the locks and he grit like spray top finish. It serves a dual purpose in my case holes whatever you’re hauling on top and absorbs most of the heat because of its porous makeup. Robert received a couple of compliments from friends and relatives and I’ve only owned the unit a few weeks. One of the influencing factors in my purchase, was a lifetime warranty and the fact that it’s made in America.

Installation was extremely easy and straight forward. The only downside was the roller adjustment was not like the video example. In the video the roller assembly fits into holes. The current cover has a , better in my opinion, has a sliding roller adjustment. This is really easy to adjust the rollers. I only wish I knew how the new system works differently than what is shown in the example video.

I’m so glad I went with this then other products out there. Super easy to install. Very sturdy and looks amazing. For me it was the ability to remove easily if needed and other covers do not have this option. It took me about 45 minutes to install by myself, which is actually pretty easy to do.

Just got mine installed and it fit perfectly right out of the box. It folds and glides very smoothly while also feeling very sturdy in every position. Looks great on my pickup.
