The Pet Gear Tri-Fold Pet Ramp by Pet Gear Inc is an easy way to help your dog to get in and out of minivans and SUV’s, climb stairs, and get up on furniture or examining tables without any heavy lifting on your part. This is a very portable and compact ramp. The tri-fold design allows this full size ramp to fold up to the size of a brief case. The textured surface of this ramp provides traction for steady footing even when wet and the raised edges help prevent slipping off the side. This ramp has rubber grippers that help keep it in place when in use. This ramp is designed for dogs up to 200 lbs. Dimensions 70” x 19.5" x 4".
