Need to secure a vending machine, coin-op laundry box, small safe, or industrial cabinet? This tubular cam lock set is a solid, affordable choice. It's made from sturdy zinc alloy with a chrome finish, and it comes with 3 keys. They use a system where 10,000 different key codes are possible, so the chances of someone else having a key that fits are super low – good basic theft deterrent. The lock cylinder diameter is about 19mm (0.75 inches), which is pretty standard. Installation is straightforward if you're replacing an old one. It's not high-security for a bank vault, but for securing vending machines, snack displays, lockers, or toolboxes, it does the job well. Just make sure the dimensions match your existing lock hole. A simple, reliable security upgrade.
