Small keys, push buttons and dials are used to lock and unlock padlocks. Combination locks are a type of padlocks, which can be unlocked only when a series of discs of letters or numbers are met to the proper alignment. Padlocks & combination locks are often used for security purposes, and most are made of metal to ensure strength. They secure a variety of valuables from relatively small items such as safes and trunks to large facilities including warehouses and apparatus storages, and also have a wide range of sizes depending on the application.
