A padlock is a lightweight lock used to secure two things together. It features a pad infused with a keyway at the bottom and a U-shaped shackle at the top.

Padlocks work by opening the lock first with the corresponding key, inserting the opened end of the shackle into the attachment holes of the two different things, and inserting the bond back into the pad.

The four main different types of padlocks are closed-shackle padlocks, long-shackle padlocks, straight-shackle padlocks, and discus or circular padlocks.

  • Closed-shackle padlocks – They are designed with a body that covers and secures most of its shackles. Due to its secured shackles compared to other padlocks, there is little space available to attach the locking hardware.
  • Straight shackle padlock – Also known as shutter padlock, it features a straight bar instead of a U-shaped shackle. They are commonly utilized in commercial settings since they are easy to fit and secure.
  • Long shackle padlocks – They boast utility more than security. This is because of their long shackles, making it more convenient to fit inside the shackles because of the bigger space.
  • Round shackle padlocks – They are also known as discus padlocks or circular padlocks, and are popular due to their absolute security. Drilling a round shackle padlock will not force the lock due to the lack of springs inside the mechanism.
