	Type A: The Type A coupler is used for applications where the continuation bar can be rotated. The ends of the bars are upset and threaded for half the length of the coupler.
	Type B: The Type B coupler uses the same coupler as the Type A system, but one bar is threaded for the full coupler length. It is designed for applications where it is difficult but not impossible to rotate the continuation bar.
	Type C: The Type C has an additional locknut and is used where the continuation bar cannot be rotated. The continuation bar is threaded for the full length of the coupler plus the length of the locknut.
