Abstract
Abstract A protective enclosure for a padlock so as to preclude line-of-sight access to the padlock. The enclosure comprises a box shaped housing which includes an access opening formed in one wall and a shackle opening formed diagonally opposite the access opening in another wall of the housing. A rigid inner partition protrudes perpendicularly from the wall in which the access opening is formed, so as to block the line of sight between the access opening and the body portion of a padlock positioned with its shackle extending through the shackle opening.
