The starter consists of a the external guide sleeve. Once the 332-inch-outside- 274-inch-diameter (73 mm) steel pipe having a nominal diameter (89 mm) pile shaft has been installed through the shaft thickness of 0.217 inch, and a 23/a-inch-outside- external guide sleeve,the pile is cut approximately 6 inches diameter (60.3 mm) pipe having a nominal shaft thickness (152 mm) above the bracket. Two 114-inch-diameter of 0.19-inch, which is shop crimped and inserted in one end (32 mm) all-thread bolts are installed into the matching hex of the piling section so that approximately 6 inches of the nuts which are shop-welded to each side of the bracket connector extends out of one end of the piling section.
