When it comes to truck lid style bed covers, there is one name that stands out above all others, UnderCover. The UnderCover Elite cover takes all the best features of their SE cover and adds a few more for extra convenience.

The Elite tonneau covers are made from an ABS composite material that is UV treated for a long life out in the harshest sun. A patented X-Effect design will keep your new bed cover from warping or cracking under extreme weather changes. This design also keeps the weight of your cover down without compromising the load capacity. An UnderCover Elite tonneau can handle over 500 lbs of weight yet the average cover weighs a mere 70 lbs!

The design of the Elite is curved at the tailgate and goes perfectly with the style of late model trucks. The OE style of the handle with the new Bolt Lock cylinder makes it unnecessary to carry an extra key because it can be custom matched to your truck's ignition key. A concealed hinge creates a tighter seal along the front of the tonneau cover and a center point lock with dual side latches improves security. UnderCover also incorporated a LED light that is removable all while being three times brighter than the original and having a slide release, you can hang the light by its fold out hook, set it up on its built in feet or use the attached magnet; finding your cargo in the dark will be a breeze. Another new feature of the Elite is the lanyard which is a handy tool that can be used to get cargo that is just out of reach but stores efficiently out of the way.

Mounting an Elite tonneau cover is very simple and straight-forward. UnderCover has designed the Elite with a clamp-on system that takes less than 30 minutes on average. The quick release struts also make taking the cover off easy if you have a large cargo load. UnderCover also includes hardware that allows you to hang the cover on your garage wall, keeping it safe from accidental damage and keeping your garage clear of clutter.

The UnderCover Elite tonneau cover comes in a contemporary textured black finish and just like all of their other covers, you can have it painted to match. Please keep in mind that the textured surface may prevent the cover color from matching your truck. You won't have to worry about the quality either since UnderCover manufactures their truck bed covers in the USA and offers a 3 year warranty to back up the quality of the cover and a one year warranty on all of the components.

The Elite is a great way for you to turn your truck bed into a good looking, secure cargo area. Order yours today, experience its great new features and you'll find out why we say UnderCover sets the standards in truck bed covers!
