Durable aluminum construction with three secure positions for truck beds.
The UnderCover Flex is a hard folding tonneau cover designed to enhance the functionality of your truck bed. This cover features a low-profile design that mounts flush with the bed rails, ensuring a watertight seal that protects your cargo from the elements. Constructed from heavy-duty aluminum panels, the Flex offers both strength and durability, making it a reliable choice for truck owners.
With its innovative front hinge design, the entire tonneau can flip up when folded, providing 100 percent access to your truck bed. The cover supports three secure riding positions, allowing for versatile use depending on your hauling needs. Additionally, the bed rail mounting system includes rubber seals and drain tubes to effectively channel water away from the bed, keeping your gear dry and secure.
Installation is straightforward with a clamp-on design that does not require drilling, making it easy to install and remove as needed. The non-lockable feature and UV protective black finish add to the practicality of the UnderCover Flex, ensuring it remains functional and visually appealing over time.
