This vehicle barrier is built from tubular steel with a non-reflective black electro-coated finish designed to cut glare and improve visibility while driving. The frame expands both horizontally and vertically to fit a range of SUVs, minivans, wagons, and crossover vehicles, keeping a dog contained in the rear cargo area and away from the driver and front seats. Easy-grip knobs paired with spring-loaded pins let the bars lock securely into position without tools, and the same mechanism allows the bars to slide down out of view when the barrier is not in use. Soft brace pads line the contact points to protect both the pet and the interior surfaces of the vehicle from scuffs. Setup is intended to take only a few minutes once the barrier is positioned against the vehicle's interior walls. The clamp-on design does not require permanent hardware or drilling for installation.
