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.

I’m very happy with my new tonneau cover. The installation was relatively easy and the instructions were clear and concise. I did watch a video that was quite informative and helpful. The only downside is it’s a bit heavy but that’s because of how well it is built.

Excellent cover so far! Only have had it on for a couple weeks but the installation is as easy as they say it is and so far it is completely waterproof. First thing i did was hose down all the seems to verify that and yes the panels support all they say it does. Definitely worth the investment. Very happy with my purchase so far!

All I can say is WOW! Installation was straightforward and easy. The slider makes this cover unique and a must for anyone looking for versatility and flexibility in a truck bed cover. I’ve had to remove all three sections to use the full bed and it took less than a minute to remove; An absolute game changer!

Well built and engineered with end user needs as the focus. I was impressed with everything! The packing, fit/finish, craftmanship and installation video were all built worthwhile. As a machine shop manager and business owner I have a unique skill set that allows me all the imperfections. Couldn't find anything worth critiquing. Refreshing. Thank you. Now onto the trials of use.

Great bed cover in all ways. Glad I bought it. Only has a slight water leak on back corners when going through high pressure car wash but better than others I have had or seen. Tough looking as well.
