These powerful magnets have 20 lbs. of pull. The heavy-duty base of the magnet is 2" in diameter and includes a protective liner to help prevent surface scratches (do not remove this liner). These magnets will work on metal doors or any ferrous metal surface and can be used to attach Cool Puppy Panels to your car.

Note: Because some vehicle doors are not 100% steel/ferrous metal, please test on your vehicle to make sure the magnets hold securely.
