When it comes to truck lid style bed covers, there is one name that stands out above all others, UnderCover. The UnderCover SE tonneau cover takes all the best features of their Classic cover and adds a few more with a new look designed to complement the lines of today's truck styles.

The SE 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 SE tonneau can handle over 500 lbs of weight yet the average cover weighs a mere 58 lbs!

The sporty ribbed design of the SE is curved at the tailgate and goes perfectly with the style of late model trucks. 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 and pull strap to make using your bed cover even easier and more convenient.

Mounting a SE tonneau cover is very simple and straight-forward. UnderCover has designed the SE 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 SE 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 SE is a great way for you to turn your truck bed into a good looking, secure cargo area. Order yours today and you'll find out why we say UnderCover setting the standard in truck bed covers!

Manufactured by UnderCover, a Truck Hero company.

This is my second cover from Undercover. I have been very happy with both. I did have an issue with the first one that was shipped but Real Truck took care of it, shipped a new one, no hassle or cost to me.

Ease of Installation
I purchased a 2015 Toyota Tundra Double Cab a few months back and needed a cover for the bed. Went to Chux Trux and they told me that they do not make the covers for this model. Heard about and they had one to fit my truck. I was worried about the shipping procedures because they told me, once you sign for it, and it is damaged, there is nothing they can do. The truck driver was great and unloaded the box like it was something special. Realtruck packed this perfectly. I opened the huge box to check out my cover and it was damage free. Directions were kind of iffy but I installed it with a buddy in about 20 minutes. It looks great.
