"Make oil changes and routine maintenance easier by lifting cars, pickup trucks, vans and SUVs up 6.25"" with the Black Widow Stackable Service Ramps. With a weight capacity of 16,000 lb. GVW per pair, this set of two durable plastic ramps is constructed with a high-impact grid design engineered for high strength without sacrificing ease of usability. Weighing only 10 lb. each, these lightweight service ramps can be transported and placed by a single person and feature built-in handles to make it easier to move them around. When it’s time to store them, the ramps stack one of top of the other to take up less space in your garage. The top curved platforms cradle tires for improved safety when the vehicle is driven up onto the ramps, and grooves on the top surface of each ramp diverts mud, rain, snow, ice and other debris. The molded traction pattern adds grips, and rubber pads on the underside of each ramp prevents the ramps from sliding on smooth floors."
