Master Lock is a popular manufacturer of combination locks that are opened using a turnable dial and a pre-selected numeral code. Combination locks are typically found on school lockers, bicycle chains and personal safes. If you have never used a combination lock before and you do not have the lock's instructions handy, figuring out which direction to turn the dial and enter the code can be a bit confusing. With a little directional help, you'll have your lock open in no time.
