- Additional rubber rail seal for redundancy
- Exterior draining gutters under panel hinge points
- Rubber lock caps keep locks free from rain and ice
No-limits access

Tectonic™ folds in the front and back for quick and easy access. It slides fore and aft just as easily, allowing unhindered access to items stowed anywhere in the bed.

- Easily translate fore and aft
- Locks in multiple positions
Use your whole bed
Zero lost bed space
Pack your bed full to the brim, and hit the road knowing that you can access everything, everywhere.

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 love the cover it’s solid. One thing I wish was an option is have hydraulic lift arms for the back panel for when you’re just loading a few things with the tailgate down or just to reach in real quick.

First time owning a tonneau cover and glad I invested in a Peragon. Purchased for security and toughness of the cover. The anesthetics of the cover gave it the extra umff to my 23' ram rebel.
Instructions and videos were straight forward to install around 1 hr for me. I had to adjust the rollers slightly but no big deal. Otherwise, was not difficult.
The panels roll and open as advertised. 😎 cool
