A centralizer assembly having a tubular body member with upper and lower channels extending around the external surface of said central tubular body member. A bow spring assembly having bow spring members is installed around the outer surface of the tubular body member and can rotate about the outer surface of the central tubular body member. Bow spring heel supports prevent the bow spring members from contacting the outer surface of the central tubular member when compressed. Non-abrasive materials prevent damage to wellhead or other polished bore receptacles. A robust bolster frame protects the centralizer assembly during shipping, storage or other periods of non-use.
