Introducing Tectonic

Game-changing strength & access

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.

Adapts for large cargo

Haul large items

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

Remove entirely

For those few times when you need complete access to your bed with nothing in the way, Tectonic removes entirely in 60 seconds by way of lift-off hinges.

Solid & Smart

All the strength without the limits

Tectonic cover close up.

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.

2022 Ford F-250

Tectonic

Very high quality cover. I replaced a more common type of folding cover after the structural rubber seals/hinges disintegrated between panels due to UV exposure and being flexed every time the cover is opened. This cover fixes that issue using external hinges in combination with static seals. The last cover was 1000 dollars and ended up in the landfill after 4 years. This cost more money but it will last the life of the truck, no doubt. This cover is also much easier to remove for full bed access. Very satisfied with the purchase.

Easy installation, less than 20 minutes. Keeps things dry and secure. Panels can be removed and reinstalled very quickly. Storage on top is very convenient. Rugged construction. Relatively expensive compared to basic covers but worth every penny.

2025 Ford F-150 Raptor

Tectonic

After researching several products, the Tectonic was the right choice. Fit, finish, and function are perfect. All materials are powder coated, not just the tops like some others, and marine grade materials are the only choice for a cover exposed to salt spray. As icing on the cake and most importantly, it looks like it belongs on my Raptor.

I purchased the Tectonic bed cover. Unfortunately it did not work with my below the rail bed tool box so I had to return it. The team at Peregon was FANTASTIC.

It truly was easy to install. Super durable and really exceeded my expectations when it comes to quality. It’s certainly not the cheapest and there’s a reason for that, this thing is amazing. It seals really well and my cargo stays dry. I also love that I can lock up my tools without any hesitations.
