I use it at the Atrey Wagon. Even if you open the rear gate when full of luggage, if you stretch it behind it will prevent the luggage from collapsing.
It is a pity that rubber will stretch in just 2 to 3 years, but we are replacing it every time.
I use it as a rack for putting waste classes (instead of futon) for the middle of the car. As this way of using rubber backwards to obstruct the rear vision. Since we had anticipated from the beginning, at the same time we purchase S hooks (KIV 0.75) by pulling up by pulling them 4 way + cross.
