The award-winning Xtra Flex forming system from Metal Forms Corp. is now available for forming concrete 12 inches high. The original system was introduced in heights of 4 inches and 6 inches for forming the tight curves often encountered in constructing concrete walks, patios, curbs and decorative flatwork. The forms are manufactured from high-density polyethylene to form tight radii from 36 inches to as small as 9 inches. www.metalforms.com
