Hook for MIM safe Variocage

I designed these for the double medium, but they will probably fit other sizes. The inner diameter is 5/8" The more closed hook is designed to slide over the top of the doors. The more open hook is designed to easily pop on and off the bars. If you want more load capacity, pass a zip tie through the hole and around the bar. If you want to make sure something cant bounce up and out (which so far hasn't been an issue in my very bouncy old jeep), I suggest placing a second hook upside down on top of the first one.
