History of the Bullet Lock

The bullet locks date back to ancient Egypt around 2000 BC. At that time, the man placed the wooden column on the door, and the latch of the door, which was placed horizontally, was above the column. The latch has a series of bumps and reeds. Push the reed up with a specific key to open the latch.

In 1848, Linus Yale (Sr.) invented the cylindrical marble lock and successfully applied for a patent. His son, Linus Yale Jr., modified it and obtained a new patent in 1861. The structure invented by Nainas Yale Jr. is very close to today's marble locks. Old high-security locks need to be paired with keys weighing up to two pounds, but with this series of inventions, the key to the high-security lock has been reduced to tens of grams of weight, laying the foundation for modern mechanical security.

Later, although the bullet lock was repeatedly challenged by the locksmith to open, but the principle of the bullet lock is still highly valued, the United States, Northern Europe, Israel have companies continue to develop new bullet locks, to prevent the locksmith to open it. Modern large-scale lock companies, but also by the founder invented a new type of bullet lock principle, and enough to build a global business, reflecting the potential market size of the bullet lock.
