Rotary Air/Electric Utility Box includes a filter-regulator-lubricator and mounts easily on any Four-Post Surface Lift (except for SM30 models) to provide quick access to utilities. The FRL helps extend the life of your air tools, and the two 110V electric outlets and air connection provide power right at your fingertips to make the lift a complete work station. 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.
