This vehicle barrier is built from tubular steel wire mesh finished in a black electro-coat that reduces glare for the driver. It spans the cargo area behind the rear seats, holding a dog in the back of the vehicle rather than roaming the cabin. Adjustable rods let the frame expand or contract to wedge securely against interior panels in a range of vehicle body styles. Rubber feet and rubber molding cover the points of contact to guard both the vehicle's interior trim and the pet from the metal frame. Installation involves positioning the frame in the cargo opening and extending the rods until it holds snugly in place, without tools or drilling. The barrier can be removed when not needed and readjusted for use in a different vehicle.
