Tectonic™ Dual-Motion Tri-Fold Truck Bed Cover
$2,499
Break free from the limits of every bed cover you’ve ever owned. Introducing Tectonic™ by Peragon®–the first ever, dual-motion truck bed cover. 26 years in the making, Tectonic™ is a solid aluminum truck bed cover with no-limits access, haul-on-top capabilities, and a lifetime warranty.
We wanted a bed cover made for more.
Unrivaled security
Keep your stuff safe
No cheap hinges, fabric or lightweight sandwich panels here. We use welded solid sheet aluminum with structural support members, brought together with hard anodized machined aluminum hinges and components.
- Two robust locks, one key
- No-tamper hinges and exterior components
- Welded .080 sheet aluminum
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.
Built to carry
No Gear Left Behind
Never run out of space again. When you've used every inch of your bed, Tectonic™ is built to carry on top.
- 400 lb. hauling capacity (on-road rating)
- Machined aluminum tie-downs

Second to none
A finish for the ages
First powdercoated and then finished with a spray-on bedliner coating,
Tectonic™ has the most durable bed cover finish Peragon® has ever created.

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.

Bed Cover Reviews
Just installed cover last night; 75 mins. Not difficult, solid instructions. I’m only reviewing to praise Heidi in customer service. Original order arrived from FedEx with single fork through the box and top ripped off. Once I sent Heidi pictures, she had new cover OTW and RA issued for pick up of old one. This is the way customer service should be! Thanks again!

The tectonic cover is a heavy duty, well designed cover that looks fantastic on my Denali. It is simple and fast to move the panels around to meet my hauling needs. Peragon stayed in contact with me before and after I received the cover to provide installation assistance if needed. I didn't need assistance as the installation was simple and fast.
Courtney and Heidi in customer service are the best! It has been so refreshing to experience the professionalism and high level of service provided by them.

So far so good. Super easy to install took under an hour, seems like it will last a long time. Time will tell if it was worth the premium price point but I do love it.
