Standard reinforcing bar hook configurations illustrate bend geometries and extension requirements for structural concrete. The ninety-degree hook specifies a twelve-bar-diameter extension alongside bend diameter parameters. The one-hundred-eighty-degree hook incorporates a four-bar-diameter extension with a two-and-a-half-inch minimum. The one-hundred-thirty-five-degree hook includes a six-bar-diameter extension with a three-inch minimum.
