Rotary Extended Ramp Chocks for use with SM300-200 Series Lifts. The chocks provide 33" more ramp length to reduce the ramp-up angle for passenger cars and motor homes with low ground-clearances. The ramps have an oil-resistant, non-skid coating, and, while two chocks are required, they are sold/priced individually. Please specify color. Local sales tax rates will apply on all Rotary Lift purchases that are drop-shipped from the manufacturer. When purchased with a lift, additional discounts may be available. Please call for better pricing. Also, freight charges for this product are NOT included, and we will contact you with the amount after order is placed.
