ABSTRACT:
A latch has a sliding bar, and multiple push bolts that each accept padlocks. The sliding bar is released by removing a padlock and pushing the corresponding push bolt. There is a master push bolt, with the remaining push bolts being slave push bolts. A master user, by removing the padlock from the master push bolt, can activate or deactivate any of the slave push bolts. Guard plates extend between and outside of the push bolts to protect the padlocks.
