  • LOCKOUT DEVICE
    Publication number: 20140060128
    Abstract: A lockout device for a handle assembly includes first and second lockout members each including an outward facing base wall and outward extending first and second projections. The first and second projections of the first base member are spaced apart to receive the handle therebetween, and the first and second projections of the second base member are spaced apart to receive the handle latch therebetween. The first and second lockout members are pivotable with respect to each other to a lockout position for engagement of the base walls of the first and second lockout members with facing surfaces of a handle and a handle latch of the handle assembly. When the first and second lockout members are secured between the handle and the handle latch in the lockout position, the first and second lockout members block movement of the handle latch to prevent rotational movement of the handle assembly.

  • PADLOCK ASSEMBLY
    Publication number: 20130276487
    Abstract: A padlock includes a lock body, a shackle assembled with the lock body, a lock subassembly disposed in a cavity in the lock body, and a shackle retainer assembled with the lock body. The lock subassembly is operable between a locked position securing the shackle in a closed position and an unlocked position permitting movement of the shackle to an open position. The shackle retainer extends into a first shackle bore and is received in a recess in a first leg of the shackle. When the shackle is in the open position, the lock subassembly is manipulable to be moved from a first position to a second position to generate a space in the cavity aligned with the shackle retainer, such that the shackle retainer is extendable into the space for disengagement of the shackle retainer from the first shackle leg recess.
