Undercover FLEX

Flex combines the best of both worlds, the security of a hard locking cover and convenience of a soft roll up cover. Constructed from the best materials available, Flex will withstand the abuse Mother Nature throws at it and keep coming back for more. The Flex cover features a sleek black profile designed to add a touch of style to most any pickup truck


The UnderCover Flex offers the best in function, providing bed protection and improved gas mileage up to 10% by way of its well-conceived aerodynamic design. The Flex cover gives you full access to your bed and with the built in props that secure the cover in an open position allowing you to carry larger loads without removing the cover. Flex is also adjustable to the size of your load; if only 2/3 of the bed is needed, Flex provides built in straps and buckles with lock rod to hold the cover in the 2/3 open positon. ONE tool Install Secure Design – Plastic buckles and straps are included to secure the panels in the partially open position. FRP Composite Panels – Lighter, stronger and higher dent resistance than aluminum. Weather Resistant – Rubber seals and drain tubes channel water away from and out of the bed. No Drill Install – Clamp-on no drill installation on most applications.


Initial installation can be completed with one ½ wrench by virtually any Do-it-yourselfer in as little as 20 minutes with no drilling or cutting, instead utilizing a clamp system around your truck's box rail. Easy Removal, entire cover can be removed in seconds with no tools needed. Reliably tight and secure, the UnderCover Flex protects the contents of your truck bed from all weather conditions within a temperature range of -20°F to well into the triple digits. Additional features include availability for a wide range of pickup models and makes, the ability to open the tailgate while the cover is on and accommodation during installation of bed liners.

5.0 out of 5 stars Just as I expected!
Reviewed in the United States on 15 August 2016
I ordered the product on 8/9 and receive it on 8/11. I was a bit concerned when the package arrived since one of two straps securing the box and contents was missing and the box itself was not entirely secured on one end. However; all contents arrived unharmed. This is the first bed cover I have installed so installation probably took me longer than it should have; but overall the installation was not difficult. I had to adjust the cover rails and clamps a few times before I got the cover sitting on the bed like I wanted it. I love the look and it works great so far. Seems very solid; and with a Pop and Lock tailgate lock my truck bed is now secure.
