Yes it is. It is a BAK Flip F1 cover that is made of a composite material. It is strong enough that a 300 lb person can stand on it, if needed. So far, I like it and it does a great job of sealing the bed. The only part that I have to think about is that it is recommended that you close the tailgate first, then latch the top down, since it goes over the tailgate lip. My work place requires that the cover be opened when you enter or the security has to loook under the cover. The guards are not aware of the things that they would have to do to open the tailgate and then close it. So, I fold the cover up to an open position before going to work every day.
