ABUS Granit™: one of the world's most secure padlocks with a tensile resistance of over six tonnes. Granit locks have a tensile resistance of over six tonnes, making it almost impossible for attackers to release the shackle from the lock body by force.

Abloy grade 3 padlocks medium strength brass padlock with chrome finish are suitable for storage doors, gates, boats, protective bars, roller-shutter doors and much more. PL330 padlocks feature an 8 mm, hardened boron steel shackle. They are also available with non sparking brass or stainless steel shackle.

Originally Invented by the Roman Empire The Romans were the first people to come up with the concept of padlocks around 500 BC. They created iron locks with metal bolts that held them closed. Keys were required to open these locks.

What they meant to ask is a “5 pin padlock”. This basically means the lock has at least 5 spring loaded pins which lift up and down depending on the shape of your key. With 5 or more it makes the lock difficult to pick and therefore more secure (see image).
