Rotary Lift column base plate covers, No. N539, fit standard Rotary Lift SPOA10, SPOA9 (200 series and above) and SPOA7 (200 series and above) lifts. The covers enhance the overall look of the lift and help keep the anchor bolts free of debris. The black plastic covers feature an embossed Rotary Lift logo. No tools are required for installation; the covers simply slide over three sides of the column and are held in place by tabs on the fourth side. They are sold individually.
