CyberLock electronic access control technology has been incorporated into two smart padlocks: the Hockey Puck and the Bar Bell. The electronic Hockey Puck Padlock has a stainless steel body that completely surrounds a stainless steel shackle when closed. Its buried shackle prevents attacks from bolt-cutters. The electronic Bar Bell Padlock has a stainless steel core and locking post. It is environmentally sealed with “O”rings to prevent water and dirt from reaching the inner core of the lock.
