Of course I want to be able to carry straps, shackles, tire plug kits and other necessary items needed when out in the middle of nowhere and I wanted to be able to secure the storage container so it's not bouncing around.
I used some 1/8" x 2" flat stock that I welded to the cage and bent it so that it would be low to the bed floor of the Jeep. I drilled and tapped some mounting holes.
