Whether you need to haul bulky furniture or transport groceries, your truck is your indispensable partner. But even though your vehicle is extremely tough and reliable, it wouldn't mind a little bit of help and protection. And that's what hinged tonneau covers are made for. Functioning like a trunk lid for your truck bed, a hard-shell hinged tonno offers multiple benefits: it securely protects your cargo, it is easily removed and amazingly strong, and it can be used with one hand. Some may say that hinged covers are difficult to install and heavier than other types of covers. Well, maybe, but not when we are talking about the UnderCover products.

The Elite LX is the newest factory painted cover from UnderCover. The LX comes standard with all the features from the UnderCover Elite. Starting with a completely new design, adding the handle to the back with a BOLT Lock making it codable to your trucks factory ignition key. The Elite LX cover includes Lanyard handy tool, that allows you to easily access cargo that is just out of reach, and when not in use, it stores neatly out of the way. It also has a new, brighter, and removable LED light. They’ve added a premium carpet lined underside, topped with a flawless paint match to make the LX the sharpest tonneau on the market. Engineered to provide a precise fit and finish to your truck bed. They have made America’s most popular tonneau cover even better.

This tonneau cover is manufactured from the lightweight yet durable ABS plastics and polymers. It weighs in at around 58 lbs, which means this is the lightest hard-shell cover on the market. However light the product is, that doesn't mean it's fragile. It can take a beating. Why? There are two reasons for that. First, it's all about the applied material: ABS is widely used in the auto industry because of its amazing impact resistance and toughness. Second, the cover has a strong X-effect understructure that made it possible to reduce the material mass without compromising the product's strength.

Having this cover installed, you can rest assured that water won't reach those things you carry in the truck bed. The product features a full-perimeter, weather-tight gasket seal that provides reliable protection when you're traveling in inclement weather conditions. And even if you live in a hot-as-hell state, this cover will easily withstand the desert sun. Thanks to the materials and design, it is capable of handling extreme temperatures without any warp or damage. What also makes this cover so much reliable are stainless steel twist latches that will make sure not a single would-be-thief can reach your cargo.

Custom-designed to fit your truck like a glove, the cover can be installed in 30 minutes – just clamp the brackets on, set the cover on the truck bed, make the necessary adjustments, and you are ready to head off. In the open position, the cover will be supported by two sturdy struts, while the super-bright LED light will illuminate your truck bed, allowing you to easily find whatever you're looking for. The LED light uses a self-contained battery power source, so there's no wiring involved. When you need to haul a bulky item, you can take the cover off in like 5 minutes thanks to the quick-release system, and hang it on the wall (the wall-mount hardware kit is supplied). And don't forget that all UnderCover tonneau covers are manufactured in the USA and come backed by a 3-year warranty.

UnderCovers not painted at the UnderCover factory are excluded from the lifetime paint warranty.

CAUTION:
Do not attempt to drive with your cover in the open position or tie down your cover while in the open position. When hauling material that is taller than the truck bed height, you should remove the cover, store it, and then properly haul oversized material. Tying the cover down when open will cause severe stress to the front hinges and could cause one or both of the hinges to crack and possibly tear out. This type of damage is not considered a manufacturer defect. Always read the ingredients of any product you are using to clean your UnderCover tonneau. Use only products that are safe for use with plastics. Many chemicals contain material that will permanently discolor your tonneau. This is not considered a manufacturer defect.

OWNER RESPONSIBILITIES:
Incidental or consequential damage or loss of contents due to use, neglect, lack of maintenance, misuse, or abuse of the UnderCover tonneau is the sole responsibility of the truck owner and operator. Paint wear to the truck’s bed can happen with the use of any truck bed cover, and is the sole responsibility of the truck owner. Materials such as 3M Scotchgard™ or other clear paint protective films may be used to help prevent possible paint damage. Ask your dealer for other recommendations. Paint damage to your truck is not covered under this warranty. When in the closed position, your tonneau must be locked and the tailgate must be closed. Failure to do so could result in sudden opening of the tonneau cover from unexpected heavy winds, which could cause damage to the truck and/or your tonneau cover.
