Security levels for commercial and residential applications.
Shackle Type
The shackle is the u-shaped metal bar used to attach the lock to the hasp or chain. There are two styles of shackle shown below. When selecting your padlock it is important to consider the distance that you will have to secure the shackle into the lock. In principle, the shorter the shackle the less vulnerable the padlock is to attack.
Consequently a closed shackle padlock will be more secure than a long shackle padlock.
Application
All our padlocks are suitable for indoor use, however for outdoor use we recommend using a laminated or marine grade padlock to reduce the risk of corrosion.
Our marine grade padlock has been designed specifically for locations close to the sea and has undergone a 1000 hour salt spray test.
