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
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.

This is the best most secure bed cover you can buy. I put it on my new ZR2 and it looks like it was made for it. What an awesome product.
Very easy to install and easy to remove if necessary.
Thanks Peragon for a great product!

Ordered another brand of truck bed cover, did not see this one available when I searched the internet on my first go around. Anyway received the other cover and was disappointed because the plastic pieces of the bed cover were attached with rubber inserts. Installed the first cover and ended up taking it off the truck and returning. Searched for the second time for a better product for my needs and came across the Peragon Techtonic cover. I plan on towing a car trailer and also a horse trailer, I feel safe leaving my tools and horse equipment in the back of the truck with this cover. Good job on the packing the item and fitment of the product. I don't ever fill out these types of reviews, but I give this product a 10 for workmanship and quality of the item. This is an expensive item, but really is well worth spending the extra money on the truck cover.
