Tri-Fold Tonneau Covers are a "best-of-both-worlds" cover. They are available in hard or soft folding styles, so you can get a cover that more accurately fits your needs. What is most unique about this style of tonneau cover is its fold-up 3-panel design. Because of the panel system, these covers are better sealed against weather and harder to break into than some other cover styles, as they have fewer weak points.
The UnderCover Flex is one of the more popular tonneau covers on the market and is well known for its strength. Each panel is made of a high quality FRP composite material, which is stronger, lighter and more durable than aluminum.
Another unique feature of the UnderCover Flex is its water tight seal and drain tubes that funnel water away from and out of your truck bed. Its design makes it one of the most waterproof covers available, so you know your cargo will be protected.
Tri-Fold Tonneau Covers generally have 3 locking positions: full coverage, 3/4 bed access and full bed access. Some covers, like the UnderCover Flex, can opened by one person from either end of the vehicle to provide easy access to the front or back of the truck box.
The panels automatically latch, ensuring full security and simple operation. To open or close most Tri-Fold Tonneau Covers, a latch or handle releases the locks for easy access, and once your tailgate is locked, your truck bed is secure.
