Keyed alike flexible shackle padlocks restrict access to property and have a long, braided steel shackle. The shackle wraps around items, so they're used where shorter or solid shackles aren't suitable. These padlocks have a longer shackle than other styles, making them less secure than other types of padlocks, so they're typically used to deter access or show evidence of tampering. They're commonly used on guns or small tools and equipment. These padlocks are keyed alike, so users can use the same key for different locks in a set.
