ABSTRACT:
A latch apparatus includes a spring pack assembly for returning a latch to its normal non-use position. The spring pack assembly includes a holder portion and a cap for retaining a torsion spring. The holder portion includes retaining members and an annular member extending upward from the base of the holder for retaining and positioning the torsion spring. The adapter portion extends opposite the retaining members and annular member to receive a spindle for actuating the handle. The spring pack assembly inserts under a latch plate on the surface of the door and can be positioned so that the handle can be actuated in either direction and return to its non-use position and so that the handle can be oriented either to the left or right and either pointing upward or downward when not being used.
