With more than 100 reuses, the Xtra-Flex radius forms are designed to shape tight radii for walkways, patios, curbs, and decorative flat-work. A standard 10-foot length will form a 38-inch diameter circle, and even can be further bent to achieve a radius as small as 6 inches. Constructed of high-density polyethylene—which doesn't absorb water—setting and stripping are easy with no nails. The stake pocket locking knob permits vertical adjustment without tools.
