Install the Twistep in minutes, and you’ll never be more than about three seconds away from one-handed, twist-out convenience. No fumbling with step stools, or unloading or unfolding cumbersome ramps. Just lift a pin, and rotate Twistep out for use. Then it folds 180-degrees to stow under the bumper, ready for the next use. With high-quality, powder-coated construction and a durable, non-slip surface, the Twistep can hold up to 400 pounds. That means it’s also great for humans, the easy-to-use solution for reaching that roof rack. Dogs take to it quickly, and customers love it. One veterinarian says: "If all my clients with big dogs used this product, I’d see less animals for flare-ups and slipped disks."
