PVI Rear Door Van Ramps are easy to install and stores vertically inside the van doorway. Manually operated with spring assist, van ramps can easily be operated by one person. Because van ramps mount to the floor inside the van doorway, they are not compatible with vans that have stow away seating. Features include three sections; durable welded construction; anti-slip, high traction surface; 600 lbs capacity; and a limited lifetime warranty. Van ramps accommodate a variety of wheelchairs and scooters. A conversion kit is required if the rear door opening contains a threshold.
