PetStep II Multipurpose Folding Pet Ramp The PetStep II pet ramp is easy to open and close plus it's lightweight - weighs only 18.5 pounds. This pet ramp measures 70 inches long (35 inches folded) 18 inches wide with raised edges and can hold up to 500 lbs of dogs, sheep, cats, goats, and even scooters. We stood on the PetStep II pet ramp (one of us weighs 190 pounds), bounced up and down and saw very little flex. The new non-slip surface is great going up and down. No slipping and sliding. The rubberized ribbed surface grabs dirt so less inside the vehicle. Soap and water for easy clean up. The PetStep II Pet Ramp accommodates a vehicle height of up to 37 inches. We like it. Features include: Ribbed non-slip surface with unique rubberized coating safe for all pets Simply swing open and close in one second (no hardware or setup required) Safe for all pets and owners 70 inches long (35 inches when folded) and 18 inches wide - weighs just 18.5 pounds Safely holds any weight dog Reduces arthritis & dysplasia pain Floats in water, will not sink Portable (balanced ergonomic handles on both sides) No materials used that can trap odors Universal non-slip grip fits all vehicles and edges Will not rust or corrode, washes with soap & water
