The unique features of the Extreme Green system allow the golfer to adjust the slope of the green with the push of a foot. By pushing the side wedge in on one side of a segment, two things happen; one side is raised while simultaneously lowering the other side. This action allows consecutive segments to be adjusted to the desired slope or brake of the practice putting surface. Constructed with an anodized aluminum base and high impact plastic components Supported in the center as well as on both sides Each segment has 16 available settings
