What are padlocks?

Padlocks consist of a U-shaped shackle, a body which harbours the locking mechanism and the locking barrel (also referred to as a tumbler. When a key is inserted into the barrel and turned the mechanism releases the shackle (secured by notches) allowing the lock to be removed. When locked the mechanism secures the shackle in place preventing it from being pulled upwards to release.

Why padlocks?

Padlocks are used to secure gates, doors although they can be used to secure toolboxes, filing cabinets as well as securing vehicles and machinery with the use of chains. They can be used with or without other, conventional locking mechanisms.

Considerations when choosing a padlock

• Size - This can primarily depend on the size of the clasp and the weight of the item that you want to secure. For example, a small cupboard would only need small sized padlock with a thinner shackle to protect from opportunists, where as industrial shipping containers would probably require a heavy duty circular padlock to protect from both damage and the use of tools to force open like bolt cutters.

• Type - Some padlocks are more secure than others, so choosing the right type is important depending on application. Securing a motorcycle chain would require a heavy duty padlock, with a closed shackle, not only to deal with the weight of the chain but to combat professional thieves using saws and cutters on the shackle.
