A closure bucket adapted for loading onto the wheel includes a root portion, a platform and airfoil, the root portion formed with a pair of radially inwardly extending laterally spaced tangs, the tangs each formed with a pair of radially aligned retaining pin holes, the retaining pin holes located radially inwardly of the male dovetail configuration.
