It is a ratchet spinner that converts the insertion angle of 1/4SQ (6.3SQ) to 3/8SQ (9.5SQ).
The height can be reduced rather than combining ratchet spinners and conversion adapters.
It is ideal for temporary tightening and early turns until you can send ratchet gears while converting the insertion angle.
