An improved hasp seal lock assembly includes a base member that is attached via a hinge to a cover member. The cover member can be rotated approximately 180° from a fully “closed” position, which is when it overlays a latch and seal, to a fully “open” position. The base member and the cover member each have a plurality of apertures defined in adjacent side walls that allow the horizontal latch arm to extend through the assembly. The base member and the cover member also include a second plurality of cooperating apertures whereby the base member and the cover member may be locked together by use of a padlock. In the preferred embodiment, each cover side wall includes a tab and tab-receiving apertures are defined within the base member. The tabs require that the cover be lifted vertically prior to rotation of the cover member about the base member.
