300.16(A) does state that the fitting should have a separately bushed opening for each conductor, but I've never seen that done.
One sees it on weatherheads, and we use cord grips with multiple holes when going into a box. But when pulling in open chases between arrays, I'm thankful I've never see this enforced.
