Abstract

A latch handle (20) includes a grip portion (22) and a housing portion (24) with a spindle (28) extending therefrom to actuate a latch. The handle (20) rotates about an escutcheon (26) and is configured for receiving two or more padlocks. The handle grip portion (22) includes a padlock receiving portion (32) while the escutcheon (26) has a raised portion (34) aligning with the lock receiving portion (32). The escutcheon (26) takes on a second embodiment (126) for rotation in an opposite direction. A defeater device (30) includes a retainer (40) coupled to a plunger member (50). The plunger member (50) slides axially within a bore (70) and rotates relative to an insert (60). The insert includes a cammed surface (62) which receives tabs (52) of the plunger member (50). The plunger member (50) is biased by compression spring (48) and torsion spring (56) to urge the tabs (52) against the cammed surface (62) so that the plunger member (50) moves axially as the retainer (40) is rotated.
