Description

Choosing a tonneau cover for your truck can be extremely difficult given the number of choices available in today's market. Most covers will require you to compromise on either security or access to your truck bed. If you're the kind of truck owner that needs a secure cargo area, but also needs the full truck bed, then an UnderCover Flex tonneau cover may be the right choice for you.

The Flex truck bed cover is made from fiberglass reinforced panels with an aluminum frame. UnderCover chose to go with this type of panel since they are stronger, lighter, and very resistant to dents or scratches. The cover clamps onto the rails of your truck bed, giving the Flex a super low profile appearance. UnderCover has also added prop rods to hold your cover in the upright, folded position which allows you to use the full truck bed. The folding section can even be removed without any tools if you are hauling a load you need to keep an eye on.

Mounting your UnderCover Flex cover will be one of the easiest thing you could possibly do on your own. The only thing necessary for installing the cover is a 9/16" wrench. Trucks without drain holes or with a bed liner may need to do some minor trimming or drilling to get everything installed properly. Once you have this tonneau cover installed correctly, the rubber seals and drain tubes should keep your bed nice and weather resistant. No cover can be 100% watertight but the Flex is pretty close!

With the number of different tonneau covers out there, there are a lot of factors to consider. UnderCover has always been a leader in the tonneau cover industry and all of their bed covers are made in the USA and backed by a 3 year warranty. Once you weigh all the functionality, security, and manufacturer history that comes with it, choosing an UnderCover Flex tonneau cover should be an easy decision for you to make!

Manufactured by UnderCover, a Truck Hero company.

I priced these out here in Phoenix and even with a Veterans discount REAL TRUCK beat them by over $200. Installation was pretty easy to do did it by myself. Only thing I have noticed is the back latch panel area due to the extensive HEAT here has melted the weather strip a tiny bit. Now it's nothing bad and with 115 degrees outside it's not the products fault. Overall I give this product 9 out of 10. I have friends and members where I work asking where I got it.

In addition I have added the Bedrug and tail gate carpets, these makes a great addition to the cover!

Thank you for all of the help so far REAL TRUCK!
