The TracRac Toolbox Mount Kit allows you to mount your saddle style toolbox without any drilling or bolting. The mount attaches to the underside of your toolbox allowing it to slide back towards your tailgate or off your truck quickly and easily. It works with most toolboxes. Check to confirm that the belly of your box fits between the TracRac base rails. (on most trucks, the width of the belly of the box, needs to be 61" or less)
