Clear Visible Euro Lock

A Pin Tumbler is the most common and widespread lock in the entire world, bar none. The main mechanism revolves around a cylinder with an outer casing and an inner casing.

The outer casing, contains a ‘plug’ which must rotate in order for the lock to open. The key adjusts the pins to the correct height, called the shear-line.

Once all these pins are in the correct height, the inner plug is allowed to turn and the lock can be opened.
