In accordance with the present invention, an anchor assembly is described for use in association with double- and single-keeper padlocks that substantially strengthens such padlocks to withstand prying leverage moments applied at the crown of the shackle. Such padlocks have an upper registry surface through which a shackle disconnectably connects to define locking and unlocking positions. In accordance with apparatus aspects, the anchor assembly comprises: (a) first and second reduced side wall notch segments along the lengths of long and short legs of the shackle positioned exterior of the padlock casing, each notch segment being bisected by a normalizing plane through the U-shaped working area of the shackle and including a pair of side wall shoulder surfaces coextensive with other and recessed wall extending therebetween, and (b) a planar base member also exclusively positioned exterior of the padlock casing, having first and second end regions each including coextensive broad surfaces separated by the thickness of the base member. When the shackle is locked relative to the upper registry, the pairs of side wall shoulder surfaces of the notches are disconnectably connected to the broad surfaces of the base member whereby irrespective of the application direction of prying moments at the crown of the shackle, at least half of each of the pairs is placed in compression thereby the associated pry force works against itself and strengthens the padlock against release. Method aspects are also described.
