PVI Wheelchair Ramps are made of lightweight aluminum. High-traction surface prevents slipping or skidding, even if it’s raining! A standard 4′ wheelchair ramp weighs 45 lbs. The new 4′ PVI ramp weights only 17 lbs. – yet both support 600 lbs. Folds into a neat package with a carry handle. Stores easily in the trunk of most cars, just like a suitcase.
