Mindy is based on zinc alloy which is extremely durable. Ideal for medium to high risk of theft, the A&AF series Mindy padlocks are recommended for a wide range of security requirements. All models in this series have a paracentric keyway, zinc alloy plated cylinder cores, and a hardened steel shackle. Unique Lock scorecard to DuplicateThe padlock comes with 3 keys which is important as the keys are too unique to duplicate easily. Hard to be Cut OffThe lock is built to resists being picked by a shim (along the sides of the shackle), and also has a unique internal mechanism that is more difficult to pick. And, because there is a metal barrier that blocks the shackle, it is also more difficult to clip with bolt cutters.
