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
- Bed-liner rubberized finish
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.
Gone in 60 seconds

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

The unpacking and installation video were very helpful. The wheel adjustment video showed a different assembly than was on my cover. I figured it out but it took a few minutes. I called customer support but you are not open on the weekends. I suspect many of your customers don’t have time to install the cover during the work week so weekend customer support would have been nice. There is a slight tear in the rubber along the side. It doesn’t impact the performance, just annoying for a $2500 cover. FedEx destroyed the top cover of the box. No damage to the product. I was worried that the rails might have been warped but they went on without a problem.

Best waterproof cover I’ve owned, install was simple (30 minutes). Their customer service is top shelf, fed ex handled shipment rough and cut a seal not a problem, sent an email and immediately got a response. New seal was sent out immediately. I highly recommend Peragon.

Awesome engineering. Had an original now backflip 20 years ago that opened from the front. Nothing else out there like this. No more crawling in the bed under the front! Even allows the back left bed handle assist without any issues. Can't wait to use camping. Already used th top hooks to haul on top. Great unit!

I’m a small man with limited mobility that still needs a big truck . The Peragon Bed cover is a game changer for me and my 2026 GMC 2500 . I am able to operate and access %100 of my truck bed . My specialized gear stays dry and clean . My local mechanic handled the install and it was so easy he didn’t charge me . It looks great and works even better . Thank you Peragon 💪🏻🇺🇸
