Lateral reinforcement consisting of an evenly spaced continuous spiral held firmly in place by vertical spacers. Spiral reinforcement should have a diameter of at least 3/8 inch (9.5 mm), with a maximum center-to-center spacing between spirals of 1/8 of the core diameter, and a clear spacing between spirals not to exceed 3 inches (76 mm) nor be less than 1 /38 inches (35 mm) or 1 1/2 times the size of the coarse aggregate.
