Abstract
A method of fabricating a rod guide. The first step involves providing a sucker rod having an exterior surface with a raised profile. The second step involves providing a split sleeve having at least one segment. The split sleeve has an interior surface with a recessed profile that mates with the raised profile of the sucker rod thereby securing the sleeve against axial movement relative to the sucker rod. The third step involves providing an overlying sleeve that overlies the split sleeve to maintain the split sleeve in mating engagement with the sucker rod.
