Great product, well designed, but unfortunately allows loose framing lumber and other smaller items to slide out. I have seen some modifications on YouTube. I like the fact it can be easily removed and reinstalled as needed. If your tailgate is locked, it can't be removed - which I found to be a clever security feature. Overall, pretty happy with it as I make the adjustment to a 5.5' pickup bed.
