What is the warranty for my Flex Cover?
Your Flex Cover has a three year warranty.
What tools will I need to install the Flex Cover?
A 9/16 wrench is the only tool required to install the Flex Cover. Flex Covers require no drilling to attach the cover to the bed. Some applications may require drilling for the drain tubes.
Is the cover waterproof? Will I have leaks?
The main feature of the Flex Cover is its quick access to the truck bed. The Flex Cover is water resistant but not waterproof. There are built-in drains to channel 99% of the water away from the bed. For a watertight bed cover we offer the UnderCover hard tonneau that may be a better alternative.
Will the Flex Cover work with my drop-in bed liner?
Yes, your Flex Cover works perfectly with most under the rail drop-in bed liners (some minor trimming may be required).
I have a spray-in liner and a bed extender, will the Flex Cover work for me?
Yes, the Flex Cover works with bed extenders and factory cargo management systems. Any additional hardware needed for the Flex Cover to mount with factory cargo management systems is included for the particular application.
What is the cover made of?
The panels consist of a top layer of FRP (fiberglass reinforced polymer). The core material is 3lb density expanded polystyrene, and the bottom layer is FRP. The seals are EPDM.
How much weight can I carry on top of the Flex Cover?
The UnderCover Flex can support 400 LBS evenly distributed.
Can I drive with the Flex Cover open?
With the Flex Cover folded forward and secured with the included straps and buckles, or folded into the upright position with both lock rods engaged, it is safe to operate your truck at normal speeds.
Where is the Flex Cover made?
Flex Covers are built right here in the USA!
What do you recommend to use to keep my Flex Cover looking new?
The FRP panels are imbedded with a UV inhibitor. Normal car wash materials will work perfectly. We offer a finishing product called Tonneau Sauce to really bring out the shine on your Flex Cover.
Can I open and close my tail gate with the Flex Cover closed?
Yes, your tail gate can be opened with the Flex Cover closed. However, the rear panel of the Flex Cover must be opened before closing the tail gate to avoid damaging the rear seal.
