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)

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

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 this cover. I decided to trade out my other cover from real truck. This cover is amazing. I hate having to unload my tools just to haul a larger item. This cover allows me to keep all my tools in the truck and still get large items to where I need them. Every time i haul things on it people ask where I got this cover. I will never switch I wish I had it years ago.

I ordered my F150 Tremor seven months ago which gave me a lot of time to research a new cover. I have had several other high end covers in the past but I based my decision to buy the Tectonic after reading reviews and watching videos. The packaging of the cover is extremely impressive along with the very clear instructions.
This cover is without a doubt the best cover I have owned. The fit and look is great and exceeded my expectations. I have several friends who own similar competitor covers and now they all want a Tectonic.

There are countless companies, which all claim to have the best. They all claim how somehow their version is better. I did my research and this company, supports veterans and law-enforcement. There was an issue with my order. They resolved it immediately I couldn’t be happier.

Purchased for a customer but thought it was a unique cover giving easier access to the front of the bed than traditional
trifold covers. Seems very sturdy. Customer support and installation videos made this an easy install for our tech.

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!
