Thank you very much for your question regarding the Safco three column box lockers, 18 lockers. This item does not come with any locks, but it does use standard locks, which are 7 millimeter or less steel shackle size. The steel shackle is the metal loop that would go inside the secure lock station on each locker.
Here are some of the 7 mm locks that we offer at On Time Supplies and there are plenty in stock for quick delivery. The combination locks do have the combinations labels on the back of each lock.
Hope that this helps! We appreciate your questions, your business and hope to be able to help you again soon!
PS. These lockers are already put together, so you just need to unbox, place where you need them and you are all set. They do not need to be put together and they do not come in 3 separate parts.
