Keep nature outside
Ready for any weather
A belt-and-suspenders approach to weather protection deploys multiple layers of sealing, creating a robust barrier to the elements, ensuring your cargo stays dry.
- Thick fin and bulb EPDM perimeter seals
- 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
Nothing out of reach
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.
- No part of your bed inaccessible
- 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.

Second to none
A finish for the ages

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.

Installation was quick and easy. Like the ease of removal as well. Not too crazy about the straps used to tie open the covers but otherwise I like it. I had backflips in the past on other trucks they were good as well but not as easy to install nor as easy to remove.

Installed on my 2026 Ram 2500 in about 30 minutes. Got the rollers snug and it works great. Feels sturdy, but folds up easily and slides smooth. Doesn’t seem to leak at all even when going through the car wash. Very happy with the purchase.

Great bed cover in all ways. Glad I bought it. Only has a slight water leak on back corners when going through high pressure car wash but better than others I have had or seen. Tough looking as well.

The cover is phenomenal! I was thrilled when I saw Peragon had released the Tetonic for my model of truck. Installation was less than an hour and super easy after watching the video.
