"Easily access the underside of your low-profile vehicle with the Black Widow Plastic Low Profile Car Service Ramps. With a 17-degree loading angle, they provide up to 3"" of lift height for low-profile cars and support up to 10,000 lbs. per pair. They feature hollow honeycomb channels to prevent moisture from building up and tire stops to ensure that your vehicle is properly positioned on the ramp. Each ramp weighs 5 lbs. each, making this pair easy to transport, position or store in a home garage or in an auto service center. Anti-slip rubber pads on the underside of each ramp increases traction on smooth surfaces."
