Square combination locks work by using a series of numbers or letters that are set by the user to unlock the lock. The lock typically has a dial or knob that is rotated to the left or right, depending on the combination sequence. The combination is set by aligning the numbers or letters on the dial in a specific order. Once the combination is set, the lock can be opened by rotating the dial to the correct combination sequence.

There are several different types of square combination locks available, including:

1.Single Dial Locks: These locks have a single dial or knob that is used to set and unlock the lock.

2.Multi-Dial Locks: These locks have multiple dials or knobs that are used to set and unlock the lock. They are often used in high-security applications where multiple combinations are needed.

3.Resettable Combination Locks: These locks allow the user to reset the combination as needed, making them ideal for situations where multiple users need access to the same lock.

4.Non-Resettable Combination Locks: These locks have a fixed combination that cannot be changed, making them ideal for situations where a single user needs access to the lock.
