When done from left hand boxes, the dancers facing in turn by the left and the dancers facing out run left. Finishes in a box circulate formation. Similar to that of turn thru and fold. The ending formation is at right angles to the starting formation.

A hinge is a half of a trade. Any two adjacent couples or dancers who can trade can also hinge. Working as a unit, each couple does half of a couples trade to end in a two-faced line at right angles to the original line.
