The Trixie Angled Protective Car Boot Bars will help to keep your dog safe when travelling (and it's also very if you are transporting other objects in the back of your car). The angled posts mean that you can utilise the entire boot area. The guard is fully adjustable in height and width. It is made from painted metal and very easy to install. There are clamps and extendable screws which wedge two posts firmly between the floor of the car and the roof. Then all you have to do is extend the horizontal bars until they reach the car windows. It's that simple!
