The locking bars together with operatively associated cam form the locking member unit which is housed in the assembly space. A cylinder assembly unit is operatively associated with the cam and comprises the usual pin and spring tumbler unit. A closing member seals the bottom of the padlock. Portions of the frame block can extend up around the shackle covering all but the center portion.
