FAQs

Is the Flex waterproof?
The Flex is weather resistant. The Flex utilizes rail channels and drain tubes to move water away from the bed. Ultimately, no folding cover is completely waterproof as there are tailgate gaps and other areas that may allow some intrusion.

What is the install time on the Flex?
The Flex can usually be installed in about 45 minutes

Can I drive with the cover in the upright position?
Yes. The Flex utilizes strut mounts to stabilize the cover while driving.

Will the cover work with a 5th wheel hitch?
Yes. There are two available cover positions while pulling a 5th wheel. Upright and ¾ bed access.

How fast can I drive with the cover in the upright position?
We do not assign a speed rating to the Flex in the upright position, but it is well equipped to handle legal interstate speeds.

What is the warranty on the Flex?
3 Years on workmanship and materials. 1 year on hardware.

Can I see out the back window with my Flex fully upright?

How easy is it to remove my Flex cover?
Simply unscrew the two elevator bolts and lift!

How can I get the side seals to lay flat on my new Flex?
After a day or two, direct sunlight will be absorbed and help the seals lay flat.

Do I need to drill into my truck when installing the Flex?
No. The Flex utilizes clamps and a no-drill installation.

Does my Flex work with a standard toolbox?
No. Flex cannot be installed with a toolbox.

How secure is my Flex cover?

Is the Flex compatible with my bedliner?
