Abstract
A locking system has a base, a receiver, a bolt assembly and at least one link member. The bolt assembly has a bolt that slides through the link members and the base, and into the receiver. The bolt assembly has an end plate with a padlock tab that projects through a slot in a plate on the link member. Each link member has another plate with a padlock tab that can projects through a slot in a plate on the base or a slot on an adjacent link member. The padlock tabs each have a padlock aperture for a padlock or a puck lock. Removal of a lock allows a user to slide the bolt out of the receiver.
