on a regular shank coupler, the shank is centered where it connects to the coupler head. overset couplers have the shank connected higher, and underset couplers have the shank lower. they are designed for situations where the coupler mount is not at the standard height, and compensate for the difference by raising or lowering the coupler head in relation to the mounting box.
