A method utilizes a locking device that includes a shackle member having a shank with a latch portion and a stop at opposite ends. A locking head mounts in a locked state on the latch portion but is removable when unlocked. A sleeve is carried on the shank but is removable. The sleeve and the shank together define a size conversion structure for the shackle. When the sleeve is on the shank, the shackle has one operative thickness to closely fit one size aperture, but when the sleeve is removed, the shackle has another, smaller operative thickness to fit a smaller aperture. A retaining member may be employed to resist removal of the sleeve. Two or more sleeves may be used to fit more than two apertures. These can be separately mountable onto the shank or may be nested on the shank, one inside of the other.
In a locking device having a locking head movable between a locked and an unlocked state, a shackle member including a linear shank having an outer surrounding surface, first and second end portions and a length and a thickness, said shackle member including a latch portion disposed at the shank first end portion and configured to engage said locking head, and a stop member disposed at the shank second end portion, a method for varying the diameter of the linear shank to adapt the locking device to variable sized apertures in components to be locked with said device, said method comprising the steps of:
