The Pet Gear Bi-Fold Pet Ramp with supertraX allows your pet easy access into your vehicle or other hard to reach places with a better grip than ever before. The removable supertraX mat is pressure activated, meaning your pet will easily be able to grip into the mat, simply by putting weight on it. The supertraX mat is much preferred to other types of carpet treads because it allows your petís paws to have a greater surface area contact with the ramp, creating greater stability. The mat is also removable for easy cleaning. Bottom grippers and included safety tether help the ramp maintain in a steady position. The ramp has a built-in carry handle for easy transportation and a bi-fold design which reduces storage space.
