6 Different Types of Padlocks
Padlocks are an integral part of people’s daily security. It has a wide range of applications, whether it is a shed, a gate, or a locker that can be used with padlocks. In addition, the padlock also acts as a visual deterrent. Padlocks have a history of thousands of years and are constantly evolving. Common padlocks can be divided into 6 categories according to their shapes and functions.
The Closed Shackle Padlock
This is a common design, which means the shackle is more protected, making it more difficult to break the padlock with a saw or other implement. The body of the padlock extends upward and surrounds the shackle. A closed shackle design is also a minimum requirement for many insurance companies. But it also has the disadvantage that the closed shackle reduces the available clearance of the padlock. So you need to pay extra attention to this before buying.
Any lock that needs to be opened with a code can be called a combination padlock. It is typically used in lockers or luggage, but can also be used for other low-level home security applications. The advantage of a combination padlock is that you don’t need to carry the key with you, and the combination can be changed multiple times. But the shortcomings are also obvious, and it is easy to be destroyed by violence.
The Straight Shackle Padlock
Straight yoke padlocks are also known as shutter padlocks because they are designed for steel rolling shutter doors. This unique design makes it an excellent all-around padlock. It is because of its high security and ease of installation that straight yoke padlocks are often used to protect shipping containers and large warehouse doors.
Long Shackle Padlocks
Strictly speaking, it is not a unique design, it just extends the shackle. Long shackle padlocks increase the locking area and are more popular. But since the shackle is the weakest point of the padlock, the increase in size necessarily reduces the level of security. So, this lock is afraid of bolt cutters and saws.
This style of padlock has a curved shackle that fits exactly around the perimeter of the object, keeping the whole in a closed state. Although its lock body itself is not strong, the discus padlock will remain locked even if the casing is destroyed.
Passive Electronic Padlock
This is a new type of padlock that was invented in recent years. It is usually used outdoors and combines the advantages of smart locks and mechanical locks. Passive electronic locks, as the name suggests, do not require a power source. It is used in the same way as a normal padlock, so you can take it with you and use it anytime at anywhere. But it also has the functions of smart locks: authorized unlocking, blacklisting, recording. Its disadvantage is that passive electronic padlocks are more expensive than ordinary mechanical locks. But from a security standpoint, it’s worth it.
