The term 'padlocked piece' can be summarized as a HASP, which is a four-letter word. A HASP is a metal loop that is secured with a padlock or other locking mechanism. It is typically used to secure doors, gates, and other items. The HASP is usually attached to the item being secured, while the padlock is attached to the HASP. This provides an extra layer of security, as the padlock cannot be removed without first unlocking the HASP.
