Unrivaled security
Keep your stuff safe

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.

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.

I love this cover. I got ti right before a road trip and it's great! Opening on both ends and the sliding movement is so convenient. I would recommend this before any other cover. YOu can tell the materials are super strong and long lasting.

I love the three panel design and the fact that it will slide forward and backward. That was my main reason for purchasing. Easy access to the bed and gear. Quick to install. Very happy with my decision. Also love that you can carry loads on top if needed.

Well packaged and easy to install. Weather proofing is good and ! stood on the cover after installing it!
Being able to open the cab side panel was one of my requirements. The benefit of being able to slide the cover when trifolded has been a huge benefit. Line-X like finish is really well done.

I chose the Perragon Tectonic cover based on convenience and capability. Easy installation and the ability for easy accessibility of item wether forward, mid or aft location when packed for gear. The bonus to this cover is the ability to store on top while traveling for some larger bulked items.

It showed up on the pallet and less than 30 minutes later, it was fully installed. Everything is as advertised. I've received nothing but compliments on it and I did get to show it off to a few curious fellow truck owners. What blows them away is when I get on top of it and jump. I ran it through a high pressure car wash and not one single drop of water in the bed (I also purchased the tailgate seal). It has exceeded my expectations so far.

Easy to unpack. Easy to install. Took less than 2 hours for the initial install including unpacking and reading the instructions. Completed the install completely solo. Looks great on my F250. Seals are doing their job keeping out the water from all the rain that we have been getting. Very good product.
