BenchTie Offers Vertical Control Point

BenchTie offers the only control point designed specifically for a vertical surface. The shank is specifically designed for a dry fit after drilling a 1/4 inch hole with a masonry or rock bit. The dimple gives a fixed location for the tip of a range pole. The body is made from a high-density impact resistant plastic that is molded around a 5" hardened spike. A recessed dimple on the top accepts the point of a prism pole for positive location. The flat surface around the dimple can be the stable location for any other measuring devices or stadia rod.
