This is a really neat little device that installs in the stake bed pocket of your pickup truck and when you are not using it stays completely flat. So actually this will work pretty well with some of the tonneau covers out there. This also works well with bed rail caps which you will see when we do an install on a vehicle with some plastic bed rail caps on the vehicle. We will go ahead and install this into the pocket on the bed rail here. You set it the way you want it and you simply tighten down the screws. There you have it, it is completely installed. Now with the flip of a switch it will be ready to tie down what you have in the back of your truck. To retract it, just simply push it back down into place. There you have it for part # WTD-810, the Bully pop-up truck hooks.
