Abus 24/90 KEYED ALIKE Stainless Steel 3-5/8" Wide Discus Padlock With Shrouded Shackle, specially designed with a distinct advantage. The disc shape effectively combats most common ways of forcing open the lock. The small opening in the shackle, minimizing shackle exposure and protects against bolt cutter attacks, making this lock extremely difficult to tamper with. This lock is made out of stainless steel, and it is ideal where security and protection against corrosion is required. This padlock is keyed alike, so orders with quantity will have multiple locks with the same key.
