The PetSTEP Folding Pet Ramp is perfect for dogs that are seniors, injured or otherwise unable to jump up or down. Your dog can enter your SUV, van, truck or trailer with ease on your dog and your back! No hardware is required; it easily opens for use and folds in half to slip into your vehicle. Advanced composite plastic construction holds up to 500 lbs-even though it is a lightweight 18.5 pounds. Universal non-slip grip fits all vehicles and edges. It will not rust or corrode, washes with soap and water. 17"W x 70"L when unfolded; 37"L when folded.
