Hard-folding tonneau cover

This cover combines functionality, convenience, and quality to provide you with the best truck bed protection against harsh weather and the elements. It also offers full cargo protection against unwanted hands.

Heavy-duty aluminum panel

UnderCover Flex Folding Tonneau Cover will serve you for a long while, thanks to the heavy-duty aluminum panel which is UV protected, solid tough and of premium quality.

Water-tight seal

The perimeter of the tonneau cover is fully fit with rubber seals. This is to prevent rain or any moisture from getting into the cargo area; keeping your truck bed always clean and dry.

3 secure riding positions

Depending on what you need and the size of your cargo, you can always choose to have the tonneau cover fully open, 3/4 way open or at full bed access.

No-drill installation

UnderCover has installed a clamp system on the tonneau, which dismisses the need for drilling during installation.

Ultra-low profile design

The ultra-low profile of UnderCover Flex Folding Tonneau Cover allows it to lay flush with the truck bed rails, which gives it a sleek look and saves on fuel.

Easy truck bed access

The tonneau opens and closes easily to enable you to access the truck bed. You can also open it partially or fully depending on what you want.

Drain tubes

The cover features drain tubes that carry water out and away from the truck bed to keep your gear area dry and your cargo safe.

Increase fuel efficiency

This cover helps in improving fuel efficiency. Its low profile and lightweight design reduce wind drag, which ultimately reduces fuel usage.

3-year warranty

UnderCover Flex Folding Tonneau Cover comes with a 3-year warranty, protecting it from defects in workmanship and material resulting from manufacturer's error.

Made in the USA

UnderCover is America's number one tonneau cover provider. It applies the best technology and uses the best quality in manufacturing the tonneaus, to ensure you get the most out of what you pay.
